The major product is tert butyl chloride as firstly isobutylchloride is formed but then hydride shift takes place due to which chlorine shift to more stable tertiary carbocation and hence the product is tert butyl chloride.

Answer:
The major product obtained when isobutane is treated with chlorine in the presence of light is tert-Butyl chloride.
Explanation:
Chlorination of alkanes occurs in the presence of light or heat. When isobutane (2-methylpropane) reacts with chlorine in the presence of light, the hydrogen atom of one of the methyl groups is replaced by the chlorine atom.
The reaction proceeds through a free radical mechanism. The chlorine molecule is homolytically cleaved by light to produce two chlorine atoms, which are highly reactive free radicals. One chlorine atom attacks the isobutane molecule, abstracting a hydrogen atom from one of the methyl groups and forming a new free radical.
The free radical thus formed reacts with another chlorine molecule, giving rise to the tert-butyl chloride.
The reaction can be represented as follows:
CH3CH(CH3)2 + Cl2 → CH3CCl2CH3 + HCl
Thus, the major product obtained is tert-butyl chloride. The other isomers, such as n-butyl chloride, sec-butyl chloride, and isobutyl chloride, may also be formed in minor quantities.

The major product is c tert butyl chloride as here firstly isobutylchloride is formed but then hydride shift takes place due to which chlorine shift to more stable tertiary carbocation and hence the product is tert butyl chloride.
