Dear Student,
 
1) Chlorination of ethylbenzene is a nucleophilic substitution reaction.
2)  Formation of major product is determined by stability of carbocation formed.
3)  When nucleophile attacks α C-atom, 2° carbocation is formed which is more stable. Hence, 1-chloro-1-phenylethane turns out to be major product.
4) When nucleophile attack β C-atom, 1° carbocation is formed which is less stable. Hence, 2-chloro-1-phenylethane turns out to be minor product.
