Question

Statement: In order for molecules to interact, they must approach each-other so closely to collide with each other.
Explanation: Rearrangement of chemical bonds occur during collision.
A. (a) `S` is correct but `E` is wrong
B. (b) `S` is wrong but `E` is correct
C. (c ) Both `S` and `E` are correct and `E` is correct explanation of `S`
D. (d) Both `S` and `E` are correct but `E` is not correct explanation of `S`.

Answer 1

Correct Answer - C
`H_(2)+Cl_(2)rarr 2H-Cl`
`H-H+Cl-Clrarr [[H,...,Cl],[equiv,+,equiv],[H,...,Cl]]rarr 2H-Cl`
They must collide each other and rearrangement of chemical bonds occur during collision.
