Question

An organic compound neither reacts with neutral ferric chloride solution nor with Fehling's solution. It however, reacts with grignard reagent and gives positive iodoform test. The compound is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Analysing the given information, we found that compound gives haloform test positive. From the options, only (a) and (c) can fulfill this criteria because it has $-\stackrel{O}{\stackrel{||}{C}}-C{H}_3$ and $-\stackrel{OH}{\stackrel{|}{C}}-C{H}_3$ groups respectively. Since the asked compound does not react with neutral $FeC{l}_3$ solution hence the correct option is (c). (a) contains a phenolic $OH$ which reacts with neutral $FeC{l}_3$ solution
