Question

Arrange the following carbocations in the order of increasing stability.
i) (C6H5)3C
+
, C6H5 = C H2 , (C6H5)2CH, CH2 = CH-CH2
ii) In SN2 mechanism inversion of configuration takes place. Explain.

Answer 1

Answer:

Stability of 1>3>2>4

Explanation:

Because benzlic carbocation is most stable than allylic carbonation.

Hence 3° benzlic is more stable than 2 and 1 bcz the positive charge more is in the resonance
