Carbocation is a group of atoms with positively charged carbon atom...
Carbocation is a group of atoms with positively charged carbon atom having six electrons in the valence shell after sharing. Carbocations are formed in the heterolysis of a bond and are planar species. Stability of
\( \mathrm{P} \) carbocation is determined by inductive effect, hyperconjugation and resonance effect. Greater the number of contributing structures, more is the stability of a Carbocation. Electron releasing groups ( \( +\mathrm{I} \) effect) increases
W the stability of a carbocation whereas the electron withdrawing groups (-I effect) have an opposite effect.
Which of the following is most stable carbocation?
(A) \( \stackrel{+}{\mathrm{C}} \mathrm{H}_{3} \)
(B) \( \mathrm{CH}_{3}-\stackrel{+}{\mathrm{C}} \mathrm{H}-\mathrm{CH}_{3} \)
(C) \( \mathrm{CH}_{3}-\stackrel{+}{\mathrm{C}} \mathrm{H}_{2} \)
(D)
