Question

In $C{H}_{3}C{H}_{2}OH$, the bond that undergoes heterolytic cleavage most readily is:

• A. $C-C$
• B. $C-H$
• C. $C-O$
• D. $O-H$

Answer 1

The correct option is D $O-H$

In $C{H}_{3}C{H}_{2}O-H$

The electronegativity order is

$H<C<O$

Thus the most electronegativity difference is between $O\&H$

Thus the bond will have more ionic character and can be break easily.

Thus $O-H$ bond will undergo heterolytic cleavage readily.
