Q68 / 180 · NEET 2013 (Karnataka) · Chemistry
Arrange the following in increasing order of stability:
(A) \(\left(\mathrm{CH}_3\right)_2 \stackrel{\oplus}{\mathrm{C}}-\mathrm{CH}_2 \mathrm{CH}_3\)
(B) \(\left(\mathrm{CH}_3\right)_3-\stackrel{\oplus}{\mathrm{C}}\)
(C) \(\left(\mathrm{CH}_3\right)_2-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}\)
(D) \(\mathrm{CH}_3-\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_2\)
(E) \(\stackrel{\oplus}{\mathrm{C}} \mathrm{H}_3\)
- Correct answerAA < E < D < C < B
- BE < D < C < B < A
- CD < E < C < A < B
- DE < D < C < A < B
Solution
The stability of carbocations increase if the number of EDG (alkyl group) is more
Hence, the correct answer is option: 'A'.
