Question

Due to electron delocalization, one would predict that the carbon-oxygen bond in acetamide, CH3CONH2, ________.A) is nonpolarB) has more double bond character than the carbon-oxygen bond of acetone, (CH3)2COC) is longer than the carbon-oxygen bond of dimethyl ether, (CH3)2OD) is longer than the carbon-oxygen bond of acetone, (CH3)2COE) is formed by overlapping sp3 orbitals

Answer 1

D) is longer than the carbon-oxygen bond of acetone, (CH3)2CO

Step-by-step explanation:

Delocalization has to to do with a situation in which electrons are not associated with with a single covalent bond in a molecule.

If a double bond is involved in delocalization, then it tends to exhibit greater single bond character. This implies that the bond will be longer than a normal double bond.

If we bring these ideas home to our particular context of CH3CONH2 and acetone, delocalization confers greater single bond character on CH3CONH2 making its C=O bond longer than that of acetone where there is no delocalization.
