At

25^{{}^{{}^{\circ}}} \mathrm{C}

, nitrogen exists as

\mathrm{N}_2

and phosphorous exists as

\mathrm{P}_4

because

Options

A $\mathrm{N}_2$ has valence electrons only in bonding and nonbonding orbitals, while P has valence electrons in both bonding and antibonding orbitals
Bhigher electronegativity of N favours formation of multiple bonds
Cbigger size of P does not favour multiple bonds
DP has preference to adapt structures with small bond angles

Correct answer

C. bigger size of P does not favour multiple bonds
