Question

An organic compound ‘X’, does not undergo aldol condensation. However ‘X’ with compound ‘Y’ in the presence of a strong base react to give the compound 1,3-diphenylprop-2-en-1-one.

a. Identify ‘X’ and ‘Y’

b. Write the chemical reaction involved.

c.Give one chemical test to distinguish between X and Y.

Answer 1

(a) Compound ‘X’ = Benzaldehyde , Compound Y = Acetophenone

(b) 

(c) Chemical test to distinguish between X and Y is the Tollen Test .

Benzaldehyde undergoes SIlver mirror test with Tollen reagent and forms silver mirror . However Acetophenone does not react with Tollen Reagent .
