Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

The correct order of stability of carbocations, is:

A

1∘<2∘<3∘<C+H31^{\circ} < 2^{\circ} < 3^{\circ} < \overset{+}{C} H_{3}

B

C+H3<1∘<2∘<3∘\overset{+}{C}H _{3} < 1^{\circ} < 2^{\circ} < 3^{\circ}

C

3∘<2∘<1∘<C+H33^{\circ} < 2^{\circ} < 1^{\circ} < \overset{+}{C}H _{3}

D

2∘<3∘<1∘<C+H32^{\circ} < 3^{\circ} < 1^{\circ} < \overset{+}{C}H _{3}

Answer

C+H3<1∘<2∘<3∘\overset{+}{C}H _{3} < 1^{\circ} < 2^{\circ} < 3^{\circ}

Explanation

Solution

More the +I alkyl groups on electron deficient carbon, more stable will be the cabocation. Hence, 3∘3^{\circ} carbocations are more stable. The correct order is 3∘>2∘>1∘>C+H33^{\circ} > 2^{\circ} > 1^{\circ} > \overset{+}{C}H _{3}
