Question

CH4 C2H2 CH3COH CH3 CH2OH CH3COH CH3COOH CH3 COOCH3

Answer 1

2CH4———>C2H2+3H2(над стрелкой t=1200-1500)
C2H2+HOH——->[CH2=CHOH]——->CH3COH(в первом случае над стрелкой Hg+,t;во второй раз «таутомерия»)
CH3COH+H2—->CH3CH2OH (над стрелкой Ni)
CH3CH2OH+CuO———>CH3COH+Cu +H2O(над стрелкой t)
CH3COH+2[Ag(NH3)2]OH——>CH3COOH+2Ag+4NH3+2H2O
CH3COOH+CH3OH<——>CH3COOCH3+H2O(над стрелкой H2SO4 и t)

Answer 2

The list of chemical compounds you provided includes various organic molecules. Here's some information about each compound:

1. CH4: This is the chemical formula for methane, which is the simplest hydrocarbon consisting of one carbon atom bonded to four hydrogen atoms. Methane is a flammable gas and is the main component of natural gas.

2. C2H2: This is the chemical formula for ethyne, also known as acetylene. It is a highly flammable hydrocarbon gas composed of two carbon atoms triple-bonded to each other with one hydrogen atom attached to each carbon. Acetylene is commonly used in welding and cutting torches.

3. CH3COH: This represents the chemical formula for ethanol, which is also known as ethyl alcohol. Ethanol is a colorless liquid and the primary alcohol found in alcoholic beverages. It is widely used as a solvent, fuel, and in the production of various chemicals.

4. CH3: This represents a methyl group, which is a functional group consisting of one carbon atom bonded to three hydrogen atoms. Methyl groups can be found in many organic compounds and are frequently involved in various chemical reactions.

5. CH2OH: This represents a hydroxymethyl group, which consists of one carbon atom bonded to two hydrogen atoms and one hydroxyl (-OH) group. It is commonly found in sugar molecules and other organic compounds.

6. CH3COOH: This is the chemical formula for acetic acid, which is a weak acid that gives vinegar its sour taste and pungent smell. Acetic acid is used in food preservation, as a solvent, and in the production of various chemicals.

7. CH3COOCH3: This represents the chemical formula for methyl acetate, which is an ester formed from the reaction between acetic acid and methanol. It is a volatile liquid commonly used as a solvent and as a flavor and fragrance ingredient.

Please note that the information provided here is a general overview, and these compounds have diverse applications and properties beyond what is mentioned.
