Question

The correct increasing bond angles order is:

• A. $B{F}_3$<$N{F}_3$<$P{F}_3$<$Cl{F}_3$
• B. $Cl{F}_3$ < $P{F}_3$<$N{F}_3$<$B{F}_3$
• C. $B{F}_3$$\approx$$N{F}_3$<$P{F}_3$<$Cl{F}_3$
• D. $B{F}_3>N{F}_3>P{F}_3>Cl{F}_3$

Answer 1

Answer: (B)

$Cl{F}_3$ < $P{F}_3$<$N{F}_3$<$B{F}_3$

Bond angles of $Cl{F}_3,P{F}_3,N{F}_3,B{F}_3$ are $\left({90}^o\right),\left({101}^o\right),\left({106}^o\right)$ and $\left({120}^o\right)$ respectively.
