Options

A. `{:(CH_(3)-CH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(2)=CH-CH_(2)-X,lt,PhCH_(2)-X),(,,,,,,):}`
B. `{:((CH_(3))_(2)CH-X,lt,CH_(3)-CH_(2)-X,lt,CH_(2),lt,PhCH_(2)-X),(,,,,,,):}`
C. `{:(PhCH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(2)-CH_(2)-X,lt,CH_(2)=CH-CH_(2)-X),(,,,,,,):}`
D. `{:(CH_(2)=CH-CH_(2)-X,lt,Ph-CH_(2)-X,lt,(CH_(3))_(2)CH-X,lt,CH_(3)-CH_(2)-X),(,,,,,,):}`

Answer

1

Explanation

The relative stability of alkyl carbocation is due to inductive effect hyperconjugation, while that of stable carbocation is due to resonance. The order is `:`
`CH_(3)CH_(2)X lt (CH_(3))_(2)CH-X lt CH_(2)=CH-CH_(2)X lt PhCH_(2)-X`
