1.	Considering x- axis as molecular axis, which out of the following will form a sigma bond. (i) 1s " and " 2p_(y)""(ii) 2p_(x)" and " 2p_(x) (iii) 2p_(x)" and " 2p_(z)""(iv) 1s " and " 2p_(z)
Answer» SOLUTION :Along x-AXIS as molecular axis, only `2p_(x)" and " 2p_(x)` can from a SIGMA bond. `2p_(x) + 2p_(y)" and " 1s " and " 2p_(z)` ALSO cannot form `sigma` bond.
