An alkane (A) `C_(16)H_(16)` on ozonolysisi gives only one products (B) `C_(8)H_(8)O`. Compound (B) on reaction with `NaOH//I_(2)` yields sodium benzoate. Compound (B) reacts with `KOH//NH_(2)NH_(2)` yielding a nitrogen (C) `C_(8) H(10)^(.)` Write the structures of compounds (B) and (C). Based on this information two their structures and identify the isomer which on catalytic hydrogenation `(H_(2)//Pd-C)` gives a racemic mixture.

Explanation

(i) As the alkene [A] on ozonolysis gives only one product [B], this means that the alkene is symmetrical in nature.
(ii) As the compound [B] on reaction with `NaOH//I_(2)` (haloform reaction) gives sodium benzoate and iodoform, this is acetophenone.
