Which of the cations in more stable ?

A
$\begin{array}{*{20}{c}}
{H\,\,\,\,\,\,} \\
{\,|\,\,\,\,\,\,\,\,\,} \\
{R' - {C^ + } - OR}
\end{array}$
✓
$\begin{array}{*{20}{c}}
{H\,\,\,\,} \\
{|\,\,\,\,\,} \\
{R' - C = \mathop O\limits^ + R}
\end{array}$
C
both equal
D
both are unstable

✓

Answer

Correct option: B.

$\begin{array}{*{20}{c}}
{H\,\,\,\,} \\
{|\,\,\,\,\,} \\
{R' - C = \mathop O\limits^ + R}
\end{array}$

b
Although $(b)$ has positive charge on $O$ (an electronegative element), it is more stable because here every atom has octet of electrons.
