Assertion : The double bond in `C_(2)` molecule consider of both `pi` bonds
Reason :Four electrons are presents in two `pi ` bonding molecule orbital in `C_(2)`

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

a

Explanation

Both are true statement and the Reason in the correct explanation of Assertion.
`C_(2):(sigma 1s)^(2)(sigma^(**) 1s)^(2)(sigma 2s)^(2)(sigma^(**) 2s)^(2)(pi 2p_(x)^(2) = pi 2 p_(y)^(2)) or KK (sigma 2s)^(2)(sigma^(**)2s)^(2)(pi 2 p_(x)^(2) = pi 2p_(y)^(2))`
The bond of `C_(2)` is `1//2 (8 - 4) = 2 and C_(2)` should be damabnet it is important to one that double bond in `C_(2)` contain of both p bond because of the presence of four elecrtron a two p molecular orbital in most of teh opther molecular a dioble bnond is made up of a single bond and a p bond.
