Question:
What is the reason for the polar nature of the carbonyl group in aldehydes and ketones?
Options:
Large electronagative difference
Small electronegative difference
Large electropositive difference
Small electropositive difference
Correct Answer:
Large electronagative difference
Explanation:
Because of the greater electronegativity of oxygen, the carbonyl group is polar, and aldehydes and ketones have larger molecular dipole moments than alkenes.
