Question

Which of the following is least reactive towards S_N1 reactions?

विकल्प

• \[\ce{CH3 - CH2 - Br}\]

• \[\ce{(CH3)3 C - Br}\]

• \[\ce{CH3 - CH(Br) - CH3}\]

• \[\ce{CH3 - Br}\]

Answer 1

\[\ce{CH3 - Br}\]

Explanation:

When it comes to one reaction, \[\ce{CH3 - Br}\] is the least reactive. In the case of \[\ce{CH3 - Br}\] the carbocation generated, which is the least stable (1° carbocation), the reaction proceeds through the creation of carbocation.
