1.	Considerting x-axis as the internuclear axis, which out of the following atomic orbitals will form a sigma bond? a. 1s and 1s b. 1s and 2p_(x) c. 2p_(3) and 2p_(y) d. 1s and 2s
Answer» Solution :The sigma bond is formed by axial overlap along INTERNUCLEAR axis and is present in the following CASES. In the case a,b and C can form sigma bond, and d canot form sigma bond. a. 1s and 2s b. 1s and `2p_(x)` d. 1s and 2s `2p_(y)` and `2p_(y)` atomic orbitals are INVOLVED in the sidwise overlap leading to the formation of `PI` bond.
