This is a Short Answer Type Questions as classified in NCERT Exemplar
Ans: In the first figure given above, the area which is under + overlapping is equal to the area under +- overlap. Both the overlaps cancel out with each other as they are oppositely charged. Due to cancelling out of the overlaps the net overlap will be zero. In the second figure given above, both the p-orbitals are perpendicular to each other. Due to the, px py orbitals being perpendicular with each other, no overlap will be possible.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.
