We know that the bonds are formed by the overlapping of orbitals. The extent of orbital overlapping depends on the size of the two participating atoms, and the valence electrons. The concentration of orbitals on the adjacent atoms in the same region is known as orbital overlapping. Complete answer : We know that the bonds are formed by the overlapping of orbitals. The extent of orbital overlapping depends on the size of the two participating atoms, and the valence electrons. The concentration of orbitals on the adjacent atoms in the same region is known as orbital overlapping. Orbital overlapping leads to the formation of two types of bonds: i) Sigma bond ii) pi-bond The covalent bonds formed by the axial overlap of s-orbitals are known as σ-bonds (sigma bond). The covalent bonds formed by the lateral overlap of p-orbitals or the half-filled atomic orbitals are known as π-bonds (pi bonds). The formation of π-bond occurs as follows: From the diagram we can see that π-bond is unsymmetrical.Thus, lateral overlap of p-orbitals leads to the formation of π-bond. Therefore, the correct answer is option (A) π-bond. Note:The extent of overlapping in π-bond is very less and thus, π-bond is weak in nature. In π-bond, the electron density is concentrated in the region which is perpendicular to the axis of the bond. A double covalent bond exists when one π-bond and one σ-bond is formed. A triple covalent bond exists when two π-bond and one σ-bond is formed.
