NEET UG CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

Consider the following statements.

I. In $F_2$ molecule $F - F\,\,\,\sigma - {\text{bond}}$ is formed by axial overlapping of two p-orbitals.

II. In $O_2$ molecule one $\sigma - {\text{bond}}$ is formed by axial overlap of p-orbitals and one $\pi - {\text{bond}}$ is formed by lateral overlap of p-orbitals.

III. In $N_2$ molecule one $\sigma$ and two $\pi - {\text{bonds,}}$ i.e., all the three bonds are formed by lateral overlap of p-orbitals.

Which of the above statements are incorrect?
