The most stable carbonium ion among the following is

The most stable carbonium ion among the following is

Options

A $\mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}_2 \stackrel{+}{\mathrm{C}} \mathrm{H}_2$
B $\mathrm{CH}_3 \stackrel{+}{\mathrm{C}} \mathrm{H}_2$
C $\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$
D $\mathrm{C}_6 \mathrm{H}_5 \stackrel{+}{\mathrm{C}} \mathrm{H}_2$

Correct answer

C. $\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5$

Step-by-step solution

Due to more possibility for delocalisation in

\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5

(of

\pi

-electrons),

\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}}-\mathrm{C}_6 \mathrm{H}_5

is the most stable ion.
