Calculate the percentage of all the monochlorinated products obtained from the chlorination of 2 - methyl butane. The relative reactivity of 1 ∘ , 2 ∘ , and 3 ∘ hydrogen to chlorination is (1 : 3.8 : 5).

Step-by-step solution

There are four different (A, B, C and D) monochloro products. Relative amount (A) (A) is obtained from the reaction of three equivalent 1 ∘ H atoms. 3 x 1 = 3.0 (B) (B) is obtained from the reaction of two equivalent 2 ∘ H atoms. 2 x 3.8 = 7.6 (C) (C) is obtained from the reaction of one equivalent 3 ∘ H atoms. 1 x 5 = 5.0 (D) (D) is obtained from the reaction of six equivalent 1 ∘ H atoms. 6 x 1 = 6.0 Total = 21.6 Therefore, percentages of the A, B, C and D monochloro products are as follows : A = 3 2 1 . 6 &times
