What type of hybridisation is present in carbocation formed during the alkaline hydrolysis of 1- bromo -1- phenyl ethane?

  • Correct answer
    A
    SP2
  • B
    SP
  • C
    d2SP3
  • D
    SP3

Solution

Alkaline hydrolysis of 1- bromo -1- phenylethane produce 1- phenylethan – 1 – ol. The reaction proceed via SN1 reaction . A carbocation is formed in the slow step of an SN1 reaction. The positively charged carbon of the carbocation intermediate to an SP2- hybridised are in the same plane. Reaction involved is as follows:

Hence, the correct answer is option: 'A'.
