Explanation:
I can't understand your questions
Molecular formula of compound : C2H4O2
The compound is used as preservatives in pickles.
The compound reacts with Ethanol and gives sweet smelling substances called as B
a) Compound A is Ethanoic acid -- CH3COOH
b) the balanced chemical equation is :
CH₃COOH + C₂H₅OH = CH₃COOC₂H₅ + H₂O.
c) Name the products formed.
esters and water
d) Name the process involved in the reaction
the process is called as esterification as ethanol and ethanoic acid reacts to form sewwt smelling compound esters
e)How can we get back the compound A from B.
We can get back A from B by hydrolysis in the presence of an acid or base.
D) The process is called as Saponification.
The chemical equation as follows is
CH3COO2H5 + H20 ----- CH3COOH + C2H5OH
