Number of isomeric compounds with molecular formula C9H10O which (i) do not dis — JEE Mains Chemistry Past Papers Chemistry Question

💡 Solution & Explanation

(A) C9H10O      Pd / H2 C9H12O (B) DU = 5 DU = 4 Observation: aromatic (phenyl group) No reaction with NaOH/KOH  no acidic group Not soluble in HCl  not aniline or ester No reaction with NaOH/KOH  no aldehyde group No reaction with 2,4-DNP  no carbonyl group Therefore only unsaturated phenyl ether is expected in C9H10O. C9H12O  O 3  o,m,p O O O O 3  o,m,p O O O
