Would you expect benzaldehyde to be more reactive or less reactive...
Would you expect benzaldehyde to be more reactive or less reactive in nucleophilic addition reactions than propanal? Explain your answer
Options
- ABenzaldehyde would be more reactive because it has a stronger electron-donating group attached to the benzene ring.
- BBenzaldehyde would be less reactive because it is more sterically hindered than propanal.
- CBenzaldehyde would be more reactive because it has a partially positive charge on the carbonyl carbon.
- DThe carbon atom of the carbonyl group of benzaldehyde is less electrophilic than the carbon atom of the carbonyl group present in propanal. The polarity of the carbonyl group is reduced in benzaldehyde due to resonance and hence it is less reactive than propanal.
Correct answer
D. The carbon atom of the carbonyl group of benzaldehyde is less electrophilic than the carbon atom of the carbonyl group present in propanal. The polarity of the carbonyl group is reduced in benzaldehyde due to resonance and hence it is less reactive than propanal.
Step-by-step solution
Correct Option is : (D)
The carbon atom of the carbonyl group of benzaldehyde is less electrophilic than the carbon atom of the carbonyl group present in propanal. The polarity of the carbonyl group is reduced in benzaldehyde due to resonance and hence it is less reactive than propanal.
