Question

Which of the following carbonyl compounds is most reactive towards nucleophilic addition reaction?

• A. 3,3,3-trichloro propanal
• B. 3,3,3-trifluoro propanal
• C. 3-oxopropane-1,1,1-trisulphonic acid
• D. 3,3,3-trinitropropanal

Answer 1

The correct option is D 3,3,3-trinitropropanal

3,3,3-trinitropropanal is the strongest electron withdrawing group among the given $-Cl,-F,$ and $-S{O}_{3}H$ group.

Thus, It is most reactive towards nucleophilic addition as carbonyl carbon is most electrophilic.
