उत्तर
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.
