Vedclass · Answer

(B) To determine the stability of carbocations,we look at the number of alkyl groups attached to the positively charged carbon atom (inductive effect and hyperconjugation).$1.$ In option $A$,the carbocation is $(CH_3)_2CH-CH^+-CH_3$. This is a secondary $(2^{\circ})$ carbocation.$2.$ In option $B$,the carbocation is $(CH_3)_2C^+-CH_2CH_3$. This is a tertiary $(3^{\circ})$ carbocation.$3.$ Tertiary carbocations are more stable than secondary carbocations due to greater hyperconjugation and inductive effects from the three alkyl groups attached to the carbocation center.Therefore,$(CH_3)_2C^+-CH_2CH_3$ is more stable.

Which of the following carbocations is most stable?
$A) (CH_3)_2CH-CH^+-CH_3$
$B) (CH_3)_2C^+-CH_2CH_3$

Which one of the following species is most stable?

Consider the following carbocations. What is the relative stability order of these carbocations?
$(1)$ $CH_3O-C_6H_4-CH_2^+$
$(2)$ $C_6H_5-CH_2^+$
$(3)$ $CH_3-C_6H_4-CH_2^+$

Compare the stability of the following free radicals:
$(1)$ $CH_3 - \dot{CH} - CH_3$
$(2)$ $C_6H_5 - \dot{CH_2}$
$(3)$ $\dot{CH_2} - CH(CH_3)_2$
$(4)$ $\dot{CH_2} - CH_3$
