Q. White phosphorus $P_4$ has the following characteristics:
Solution:
White phosphorus $\left(P_{4}\right)$ has $6 P-P$ single bonds, 4 lone pairs of electrons and $P - P - P$ angle of $60^{\circ}$. It is a translucent white waxy solid. It has large atomic size and less electronegativity. So, it forms single bond instead of $p \pi-p \pi$ multiple bond. It consists of discrete tetrahedral $P _{4}$ molecule as shown in the figure.
