Does $CO_2$ contain multiple bonds? If so,identify them.

The bonds between $P$ atoms and $Cl$ atoms in $PCl_5$ are likely to be

The bond dissociation energy of $B-F$ in $BF_3$ is $646 \ kJ \ mol^{-1}$ whereas that of $C-F$ in $CF_4$ is $515 \ kJ \ mol^{-1}.$ The correct reason for higher $B-F$ bond dissociation energy as compared to that of $C-F$ is

In carbon monoxide $(CO)$,how are the carbon and oxygen atoms bonded?

Indicate the nature of bonding in diamond.

The bond dissociation energies of $F_2, Cl_2, Br_2$ and $I_2$ are $37, 58, 46$ and $36 \ kcal/mol$ respectively. Which of these has the strongest bond?
