Question

The carbocation is $\left({CH}_3\right)-C\stackrel{+}{H}-\left({CH}_3\right)$ less stable than:

• A. $\left({CH}_3\right)-C{H}_2-{\stackrel{+}{C}H}_2$
• B. ${\stackrel{+}{C}H}_3$
• C. $({CH}_3{)}_3\stackrel{+}{C}$
• D. none of these

Answer 1

The correct option is C $({CH}_3{)}_3\stackrel{+}{C}$

The order of stability of carbocation is: tertiary > secondary > primary > methyl

$\therefore \underset{\text{Order of stability}}{{{\left(C{H}_3\right)}_{3}C}^{+}>C{H}_3-\stackrel{+}{CH}-C{H}_3}$
