Question

In the reaction

The hybridisation states of carbon atoms 1,2,3,4 are
A. 1 and 2 `sp^(2)`, 3 and 4 `sp^(3)`
B. 1 and 2 `sp^(2)`, 3 and 4 `sp`
C. 1, 2, 3 and 4sp
D. 1,2 `sp^(3)`, 3, 4 `sp^(2)`

Answer 1

Correct Answer - A
`Br-underset(sp^(2))overset(1)(CH)=underset(sp^(2))overset(2)(CH)-Br underset("Catalyst")overset(H_(2))rarrBr-underset(sp^(3))overset(3)(CH_(2))-underset(sp^(3))overset(4)(CH_(2))-Br`
