Senior 1 Chemistry Compulsory 2 Chapter 3 Knowledge Induction of Organic Compounds Volume Answers?

Organic matter is a chemical compound containing carbon (except carbonates and carbon dioxide)! Solubility depends on the specific situation, and the thermal stability is generally good! Aldehyde pre-silver ammonia can produce silver mirrors! Sodium metal can replace the hydrogen in the hydroxyl group that can break the oxygen-hydrogen bond! In water, in alcohol!

Upper subject internet café is good there.

Grasp the nature of the functional group of the waves.

Esterification reaction: Chinese acid dehydroxyl alcohol dehydrogenation.

The elimination reaction of halogenated hydrocarbons is that the halogen atom and the hydrogen on its adjacent carbon combine to form hydrogen halide, and a carbon-carbon double bond is formed at the position of the original halogen and hydrogen.

The hydrolysis reaction of halogenated hydrocarbons is the substitution of a halogen atom by a hydroxyl group.

In fact, the reaction of organic matter is inseparable from hydrolysis, esterification, substitution, addition, and polycondensation, which should be bold and reasonable

Look at the textbook and summarize it yourself You will find that you will be able to read other people's memorization, which may save time and forget it quickly.

It's easy to learn to have a machine, it's just that there are a lot of knowledge points, just look at it carefully a few times, but you must be attentive.

The organic in the first year of high school is still in its infancy, and it may not be very proficient, but it's okay, anyway, Elective 5 will focus on organic matter.

The end point of organic matter is the functional group, so it is necessary to remember the characteristics and characteristics of various functional groups, and the familiar mastery will beat the invincible opponent of chemical organism.

You can take a look at "The Golden Sun Tutorial Case".

Or ask the Golden Sun team a question.

Oxidation reaction (combustion).

CH4+2O2 CO2+2H2O (light blue flame, no black smoke) substitution reaction.

Note that light is the main reason for the reaction, and there are 5 kinds of products) CH4 + Cl2 CH3Cl + HCl

ch3clcl2―→ch2cl2+hcl

ch2cl2+cl2―→chcl3+hclchcl3+cl2―→ccl4+hcl

Methane can also substitute with bromine vapor under light conditions, and methane cannot discolor acidic KMNO4 solutions, bromine water, or bromine carbon tetrachloride solutions.

Oxidation reactions. Burning.

C2H4+3O2 2CO2+2H2O (bright flame with black smoke) ( Oxidized by acidic KM4 solution, can make the acidic KMno4 solution fade.

Addition reaction. ch2 ch2 br2 ch2br ch2br (can discolor bromine water or carbon tetrachloride solution of bromine).

Under certain conditions, ethylene can also have addition reactions with H2, Cl2, HCl, H2O, etc. CH2 CH2 H2CH3CH3

CH2 CH2 HCl CH3CH2Cl (ethyl chloride) CH2 CH2 H2O CH3CH2OH (to ethanol) Polyaddition.

NCH2 CH2 CH2 CH2 N (polyethylene) ethylene can discolor acidic KMno4 solutions, bromine water, or carbon tetrachloride solutions of bromine. This reaction is often used to identify alkanes and olefins, such as methane and ethylene.

Oxidation reaction (combustion).

2C6H6 15O2 12CO2 6H2O (bright flame with thick smoke) substitution reaction.

The hydrogen atom on the benzene ring is replaced by bromine atom, nitro group.
