maqjor product

Any temperature conditions mentioned?
At normal temperature there will be substitution according to S_N¹ mechanism..
At higher temperature there will be elimination according to E₂ mechanism..
so i think now u can make out which is the major and minor product by seeing the temperature conditions

no temperature mentioned then how?

govind won't it be E2? Both E1 and E2 follow the same rate order..3 > 2 > 1 due to hyperconjugation stabilisation.
If by E2, S_N2 will compete but fail largely. 60% E2, 40% of the other. So major is E2 product and minor is substitution product...would be helpful if we had temperature.

@Pritish that will be E₂ edited...
