B

Option 3

C

Option 2

D

Option 4

Answer

Option 3

Explanation

Solution

The stability of carbocations is influenced by several factors, primarily the degree of substitution and the availability of hyper-conjugative hydrogens.

Stability Factors: Tertiary carbocations (three alkyl groups attached) are more stable than secondary (two alkyl groups), which in turn are more stable than primary (one alkyl group) and methyl (no alkyl groups). The order of stability due to hyperconjugation and inductive effects is:

Tertiary > Secondary > Primary > Methyl.

Correct Order: The correct stability order of the carbocations is:

(CH3)3C+ > (CH3)2CH+ > CH3–CH2+ > CH3+.

Thus, the correct order of stability for the given carbocations is:

(CH 3)3C+ > (CH3)2CH+ > CH3–CH2+ > CH3+.
