The P Block Elements Ques 4
4. Nitrogen forms $N_2$, but phosphorus is converted into $P_4$ from $P$, the reason is
[2001]
(a) Triple bond is present between phosphorus atom
(b) $p \pi-p \pi$ bonding is strong
(c) $p \pi-p \pi$ bonding is weak
(d) Multiple bond is formed easily
Show Answer
Solution:
- (c) Nitrogen form $N_2$ (i.e. $N \equiv N$ ) but phosphorus form $P_4$, because in $P_2, p _{\pi}-p _{\pi}$ bonding is present which is a weaker bonding.
