Question

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

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

Answer 1

The correct option is D $O-H$

Heterolytic fission occurs when the two atoms differ considerably in their electronegativities.
$O-H$ bond undergoes cleavage most readily because $O$ and $H$ differ markedly in their electronegativity and further oxygen being highly electronegative can accommodate the negative charge more effectively developed after the cleavage.
