Question

In which of the following molecules/ions are all the bonds identical?

• A. None
• B. $B{F}_3$
• C. $C{H}_4$
• D. $N{H}_3$

Answer 1

Answer: (B), (C), (D)

$N{H}_3$

All three of them have bonds formed by the exact same type of equivalent hybrid orbitals. $s{p}^3$ in $C{H}_4$ and $N{H}_3$ and $s{p}^2$ in $B{F}_3$ One wouldn’t be able to distinguish the bonds present when it comes to length or strength. Therefore all three have ‘identical’ bonds.
