Question

Which of the following compounds does NOT undergo haloform reaction?

• A. $C{H}_3-\underset{OH}{\underset{|}{C}}H-C{H}_3$
• B. $C{H}_3-\underset{O}{\underset{||}{C}}-C{H}_3$
• C. $C_2{H}_5-\underset{OH}{\underset{|}{C}}H-C_2{H}_5$
• D. $C{H}_3-\underset{O}{\underset{||}{C}}-C_2{H}_5$

Answer 1

The correct option is C $C_2{H}_5-\underset{OH}{\underset{|}{C}}H-C_2{H}_5$

Compounds containing methyl keto ($C{H}_3-\underset{\underset{O}{||}}{C}-$) group or compounds ($R-\underset{\underset{OH}{|}}{C}H-C{H}_3$) that can be oxidised to methyl keto group can undergo haloform reaction.
