MCQ
Which of the aldehyde is most reactive $?$
- A${C_6}{H_5} - CHO$
- B$C{H_3}CHO$
- ✓$HCHO$
- DAll the equally reactive
✓
Answer
Correct option: C.
$HCHO$
c
(c) Among Carbonyl Compounds, reactivity decrease with increase in alkyl groups as alkyl groups ($+I$ effect) decrease positive character on C-atom. Thus, the correct order of reactivity is
(c) Among Carbonyl Compounds, reactivity decrease with increase in alkyl groups as alkyl groups ($+I$ effect) decrease positive character on C-atom. Thus, the correct order of reactivity is
$HCHO > C{H_3}CHO > {C_6}{H_5}CHO$
