Question

B - F bond order in BF3 is:
​

Answer 1

Answer:

1⅓

Explanation:

One model for BF 3 is a resonance hybrid of three structures, each having one double bond and two single bonds. The B–F bond is said to have a bond order of 1⅓.

Answer 2

B - F bond order in BF₃ is 1.

• In chemistry, the bond order tells the number of effective bonds between two atoms in a molecule.
• Bond orders can be 0, positive numbers, or fractions.
• In BF₃, 3 fluorine atoms are attached to a boron atom through one sigma bond each.
• Since there are no pi electrons (double bond) involved, the molecule does not show any resonance.
• Hence the bond order = Number of bonds between B and F / Number of F atoms

        = 3 / 3

       = 1
