O

Answer 2

(a) $\bold{XeO_{4}}$ contains four sigma bonds and four pi bond.

(b) $\bold{(CN)_{2}}$ ontains four three sigma bonds and four pi bonds.

(c) $\bold{CH_{2}(CN)_{2}}$ contains six sigma bonds and four pi bonds.

(d) $\bold{HCO_{3}^{-}}$ contains four sigma bonds and on pi bond.

Step by step explanation:

• Sigma bond is formed due to the overlapping of pure s-s;p-p and s-p or hybrid orbitals of two atoms along with their internuclear axis. It is a very strong bond and less reactive.It is indicated by the "$\bold{\sigma }$".
• Pi bond is formed due to the lateral or side wise or parllel overlaping of pure "p" orbitals. It is a weak bond but highly reactive. It is indicated by the "$\bold{\pi}$".
