Question

What is the major product of the following reaction?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is C

The explanation for the correct option:

Option C:

1. Alkyl halides are produced when alkenes are combined with hydrogen halides.
2. The hydrogen halides are reactive in the following order $\mathrm{HCl}>\mathrm{HBr}>\mathrm{HI}$
3. Since $\mathrm{HI}$ is an acid, the pi bond attacks ${\mathrm{H}}^{+}$, resulting in the formation of a carbocation intermediate.
4. As a result of the secondary carbocation's $1,2$ methyl shift, a more stable tertiary carbocation is produced.
5. ${\mathrm{I}}^{-}$, a weak base, will function as a nucleophile.
6. Hence, it is the correct option.

Therefore, the major product formed is
