Question
Which of the following is most reactive in nucleophilic addition reactions?
Options
HCHO
CH3CHO
CH3COCH3
CH3COC2H5
Advertisements
Solution
HCHO
Explanation:
The group linked to carbonyl carbon influences reactivity in nucleophilic addition processes. The more electron-deficient the carbon, the greater its reactivity. The presence of alkyl groups reduces reactivity by lowering electron deficit. As a result, HCHO is more reactive towards nucleophilic addition processes.
