Question

A compound A having formula C^2H^6O reacts with compound B having a smell of vinegar, produce a compound C. Compound C on alkaline hydrolysis gives back to compound A
(a)Identify the compound A, B and C
(b)name the reaction involved
(c)write chemical equation for the formation of compound C

Answer 1

A- ethanol B-ethanoic acid C- ester
esterification
c2h6o+ch3cooh----> ester +water

Answer 2

Answer:

For a: Compound A is Ethanol. Compound B is Ethanoic acid and Compound C is an Ester named as Ethyl ethanoate.

For b: The reaction is known as esterification reaction

For c: The reaction is given below.

Explanation:

• For a:

Compound "A" having formula $C_2H_6O$ react with Compound "B" which has a smell of vinegar. So, compound B is ethanoic acid or acetic acid having formula $CH_3COOH$. The recation of "A" and "B" will produce ester known as ethyl ethanote having formula $CH_3-COO-CH_2-CH_3$

• For b:

The reaction between an alcohol and a carboxylic acid will produce a sweet smelling compound known as ester and hence, the reaction is known as Esterfication reaction.

• For c:

The reaction for the formation of compound "C" is :

$CH_3COOH+CH_3CH_2-OH\rightarrow CH_3-COO-CH_2-CH_3+H_2O$
