The relative of `1^@ h, 2H^@ and 3^@ H` in bromination reaction has been found to be 1 :82 : 1600 Respectively in the reaction ,

The percentage yield of (A) and (B) are expected to be

Options

A. 99.4%, 0.6%
B. 50%, 50%
C. 0.6%, 99.4%
D. 80%, 20%

Answer

1

Explanation

`underset(1^(@))(CH_3)-underset(3^(@))overset(CH_3)overset(|)CH-underset(1^(@))(CH_3)`
Reactivity of ` 1^(@)`H is ` 9 xx 1 =9`
Reactivity of `3^(@)` H is ` 1 xx 1600 = 1600`
Total reactivity of all H.s is
`1600 + 9 = 1609`
.A. is obtained by replacing `3^(@)H` atom
`% ` of `A = (1600)/(1609) xx 100 = 99.4%, 0.6%`
