Question

The compound $N{H}_3-B{F}_3$ can be easily separated into its compounds because

• A. $B{F}_3$ is highly reactive
• B. $N{H}_3$ is highly reactive
• C. $B{F}_3$ and $N{H}_3$ are unstable
• D. $B{F}_3$ and $N{H}_3$ have their independent existence

Answer 1

The correct option is D $B{F}_3$ and $N{H}_3$ have their independent existence

$B{F}_3$ and $N{F}_3$ are different compounds with individual identity and properties. There exists a dative bond from N of $N{H}_3$ to the electron deficient B of $B{H}_3$. Hence, it can be easily separated into its compounds.
