pBlock ElementsII 1 Question 49
49. White phosphorus $\left(\mathrm{P}_{4}\right)$ has
(1998, 2M)
(a) six $\mathrm{P}-\mathrm{P}$ single bonds
(b) four $\mathrm{P}-\mathrm{P}$ single bonds
(c) four lone pairs of electrons
(d) $\mathrm{P}-\mathrm{P}-\mathrm{P}$ angle of $60^{\circ}$
Show Answer
Solution:
- The structure of $\mathrm{P}_{4}$ is
It has six $\mathrm{P}-\mathrm{P}$ single bonds.
There are four lone pairs on four phosphorus. $\mathrm{P}-\mathrm{P}-\mathrm{P}$ bond angles are of $60^{\circ}$.
