1.	What kind of a bond is formed when the orbitals of two atoms A and B undergo (i) s-s overlap (ii) s-p overlap?
Answer» SOLUTION :In both (i) and (ii) only `SIGMA`- bonds are FORMED. Because s-orbitals are non directional in nature, always overlap ALONG the internuclear axis only. So s-orbitals form `sigma`- bonds only. The `sigma`- bonds in (i) and (ii) are denoted as `sigma_(s-s)` and `sigma_(s-p)` respectively.
