The major product obtained when this alkyl halide is subjected to E2 reaction will be (a) (b) CH3 CH2 CH CH2 CH3 alc. KOH - HBr CH3 CH CH CH2 CH3 Br 2 - pentene (c)

The saytzeff product is major product in E2 elimination. The bromine will be eliminated and the hydrogen will be eliminated alpha-carbon atom. The more substituted carbon atoms will be the major product. The reaction is given below:
