IF molecular axis is X then which of the following overlapping will form `pi` bond?
`p_(z)+p_(z),p_(x)+p_(x),p_(x),p_(y),s+p_(z),p_(y)+p_(y)`

Text Solution

Verified by Experts

The allowed combination are (i) s and `p_(z)` and (ii) `p_(x) and p_(x)`. Other combination (iii) and (iv) are not allowed because they have zero overlap.
