Question

Write the number of resonance contributors (including the neutral structure) that can be drawn for B F 3 ​ , in which the F lone pairs form B = F bonds.

TestHub · Accepted Answer

Boron has only six electrons in B F 3 ​ . Each F lone pair can form a B = F double bond ( F + , B − ) : 3 charge-separated forms plus the neutral form = 4.
