When 2s orbital overlaps with 2p_(x) or 2p_(y) orbital (assuming Z-axis as the internuclear axis ), there is a partial overlap , yet they don't form any molecular orbital.Explain why.

1.	When 2s orbital overlaps with 2p_(x) or 2p_(y) orbital (assuming Z-axis as the internuclear axis ), there is a partial overlap , yet they don't form any molecular orbital.Explain why.
Answer» SOLUTION :This is bacause 2s ORBITAL weve function has same SIGN throughout but `2p_(x) or 2p_(y)`orbital weve function has + ve sign in one lobe and -ve sign in the other lobe. The SMALL ++ overlap cancels the +- overlap which being equal in area but opposite in sign
