Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

The correct order of stability of carbocations, is:

A

$ 1{}^\circ <2{}^\circ <3{}^\circ

B

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

C

$ 3{}^\circ <2{}^\circ <1{}^\circ

D

$ 2{}^\circ <3{}^\circ <1{}^\circ

Answer

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

Explanation

Solution

More the +I+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{+}{\mathop{C}}\,{{H}_{3}}
