Considering X-axis as the internuclear axis which out of the following will not form a sigma bond and why ? (a) 1s and 1s(b) 1s and 2p_(x) (c) 2p_(y) and 2p_(y)(d) 1s and 2s

Considering X-axis as the internuclear axis which out of the following

1.	Considering X-axis as the internuclear axis which out of the following will not form a sigma bond and why ? (a) 1s and 1s(b) 1s and 2p_(x) (c) 2p_(y) and 2p_(y)(d) 1s and 2s
Answer» Solution :`{:((a) 1s and 1s),((B) 1s and 2p_(x)),((d)1s and 2s):}} {:("All these THREE"),("overlap an intrnuclear"),("axis so it FORM" sigma"bond"):}`. (c) `2p_(y)` & `2p_(y)` are not overlap on intranuclear axis but remain parallel so it form `PI` bonds.
