General Organic Chemistry

The order of stability of Carbanions is \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2^{-}<\left(\mathrm{C}_6 \mathrm{H}_5\right)_2 \mathrm{CH}^{-}<\left(\mathrm{C}_6 \mathrm{H}_5\right)_3 \mathrm{C}^{-}\)

In \(\mathrm{CH}_3{ }^{+}\), Carbon carrying positive charge is \(\mathrm{sp}^3\) hybridised.

In \(\mathrm{CH}_3^{-}\), Carbon carrying negative charge is \(\mathrm{sp}^2\) hybridised.

The order of stability of Carbocations is \((\mathrm{C}_6 \mathrm{H}_5)_3 \mathrm{C}^{+}<(\mathrm{C}_6 \mathrm{H}_5)_2 \mathrm{CH}^{+}<\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2^{+}\)
