organic chemistry chpter 1 Polarity / non polarity coupling

Covalent bond is mainly a combination of non-metallic elements (mainly gaseous elements). These include polar covalent bonds and nonpolar covalent bonds. Polarity covalent bonds have electronegativity (or electron affinity) slightly different from those of nonmetal elements. Nonmetallic elements have a negative constitution, but among them, one having strong properties of + The way one element is combined. This is a way of combining the same elements with + on one side and - on the other. The greater the difference in the electronegativity between the two elements, the more polar covalent bonds than nonpolar covalent bonds. This is because the electronegativity is shifted to one side.

A nonpolar covalent bond is when a different element is in the same charge state or in the same charge state and in the same charge state, and in the case of a combination of different elements, the electrons around the atom are evenly coupled to each other. Nonpolar covalent bonds are synonymous with nonpolar covalent bonds. If the difference in the shared electron pairs of the elements is not large, it is a non-polar covalent bond. The characteristics of the covalent bond are directional (+, -), ie polar (+ and -) and nonpolar (neutralized by + and - neutral) and the molecule takes on a stereostructure - the energy of the same is offset, so the direction is weak).

Even if the same hydrogen molecule is encountered, it can be oriented so that it can have both a non-polar covalent bond of + and + and a polar covalent bond of + and - that is, two covalent bonds. Negative (δ-) and negative (δ +) electrons are positive and negative, respectively.                      Hydrogen molecules are strong in the nature of +, but also electronegativity is not perfect, so they are not perfect +, so the + and - properties coexist.

From the viewpoint of quantum mechanics, covalent bonding is due to the overlapping of the stable orbits of the hybrid orbitals. The + and - phases are alternately vibrated by the quantum mechanical phenomena of particle and wave, and when they are in the same phase, ). This is another interpretation of the combination of electronegativity and its difference, literally describing the phenomenon of the microscopic world of particleicity (+) and oscillation (-).

Thirteen immigrants protesting in 50 cities ahead of Trump's inauguration

Demonstrators of immigrants in the major metropolitan areas of the United States began to appear at the same time, six days before the inauguration of US President-elect Donald Trump.

Thousands of people participated in the demonstration, which calls for the protection of immigrants' rights and the embarrassment of Trump's election pledges, including the establishment of Mexican border barriers and the ban on Muslim entry.
Politicians, religious leaders, and women and labor groups also joined the protests. Washington, DC, Chicago, California Los Angeles, San Jose, Phoenix, and 50 cities across the country, big and small rallies and demonstrations took place.



The protests in Washington DC began with a rally in the Metropolitan AME church. Max Kim, a 19-year-old immigrant from Korea, said, "Many people are ashamed of their status because of hatred and intolerance of immigrants and refugees, but I am not ashamed of that status. "I am constantly reminding myself that this is happening."

Trump White House may be kicked out of reporters.....

Reviewing previous plans outside the White House of the Press Room ... "The press is an opposition party, the White House has to go out" WASHINGTON (Reuters) - White House journalists may be kicked out of the White House press room, according to a report by the American men's magazine Esquire.

It is being considered to move the press room outside the White House to the "White House Conference Center" or to the old administration building. It seems that Donald Trump has nothing to do with the election of the president


White House spokesman Sean Spy said, "There is no decision," but "There was some discussion about what to do."


He told the White House press room space that it is enough to cover the presidential election, saying that "media attention is very important to cover President Trump." "I have been asked to attend the press conference at the time of the last press conference, but I was limited to 400. Is there any opportunity for more journalists? I am discussing that," he added.


The reason for this is that the current White House press room is considering a way to secure more space because it can not cope with the demand for coverage for Mr. Trump. But another senior official said the press is the opposition party, saying that they want to get out of the White House. Trump 's "avoidance of the press" is famous. Trump, who criticized the media for being dishonest and full of prejudices against him during his presidential campaign, made his first appearance after the presidential election victory on November 11. In a 58-minute interview at Trump Tower, he told CNN and the Internet media Buzzfeed, who reported "Trump X Files," that he was "an embarrassment" and "a pile of failed trash." CNN Jim Acosta, Your company is terrible. "

Johnny Depp gets divorced on allegations

Johnny Depp gets divorced on allegations

Hollywood actor Johnny Depp (53) has filed a lawsuit against his former wife, Amber Hudd, but filed a lawsuit against his wealth management company and turned to court.

According to the Associated Press and the British Guardian, Los Angeles (LA), the US court, accepted most of the consensus of both sides on December 13, Deb gave $ 7 million (8.2 billion won) alimony to Hudd, Including real estate and automobiles, including mansions.

Hudd claimed that Deb had been violent to her, and in August of last year, 18 months after marriage, she agreed to a divorce and dropped a domestic violence suit



Since then, legal proceedings have been continuing with the payment of alimony.




Hurd said he would donate his alimony received from Deb to a charity, and he said that the two dogs that he grew up with, the dog pistol and the horse and horse, were raised by Hurd.

Deb and Hudd have been in conflict with the Australian government since last year when they entered Australia with a private plane and did not report the pistol and wealth to the quarantine authorities.


Deb, on the other hand, filed a $ 25 million ($ 29.4 million) lawsuit against the Managment Group (TMG), an asset management firm that has managed its income for the past 16 years, and its CEO Joel Robertsman


Dept said that TMG did not pay taxes properly, received unauthorized loans, and spends tens of millions of dollars in oversight on services such as security.

He alleged that he had suffered damages from TMG's "total management mismanagement," accusing him of 11 charges including fraud, breach of contract, and work-related negligence.

"TMG has taken over debts' assets, TMG and third parties have been able to use their revenues as they wish," Deb said. "I hired a new fund manager last year.

"It's all a fictional story," TMG said. "The company refused to let Deb be irresponsible and did his best to protect him from the wasteful spending."
