MCQ
The correct stability order of carbocations is
  • A
    $\left( CH _3\right)_3 C ^{+}> CH _3-\stackrel{+}{ C } H _2>\left( CH _3\right)_2 \stackrel{+}{ C } H >\stackrel{+}{ C } H _3$
  • B
    $\stackrel{+}{ C } H _3>\left( CH _3\right)_2 \stackrel{+}{ C } H > CH _3-\stackrel{+}{ C } H _2>\left( CH _3\right)_3 \stackrel{+}{ C }$
  • $\left( CH _3\right)_3 \stackrel{+}{ C }>\left( CH _3\right)_2 \stackrel{+}{ C } H > CH _3-\stackrel{+}{ C } H _2>\stackrel{+}{ C } H _3$
  • D

Answer

Correct option: C.
$\left( CH _3\right)_3 \stackrel{+}{ C }>\left( CH _3\right)_2 \stackrel{+}{ C } H > CH _3-\stackrel{+}{ C } H _2>\stackrel{+}{ C } H _3$
(C)
More no. of hyperconjugable Hydrogens, more stable is the carbocations.
