Question

Which of the following best describes the C=O bond compared to a C=C bond?
Options
A Longer and weaker
B Shorter, stronger, and more polar
Correct Answer
C Same length and strength
D Longer but stronger
Correct Answer

Option B is the correct answer.

Detailed Explanation

The C=O bond is shorter (1.23 Å vs 1.34 Å), stronger (178 kcal/mol vs 146 kcal/mol), and more polar than a C=C bond due to the higher electronegativity of oxygen.

Hint

Oxygen is more electronegative than carbon.
