Question

Select the most appropriate statement In $B{F}_3$

• A. All the bonds are completely ionic
• B. The B-F bond is partially ionic
• C. B-F bond has partial double bond character
• D. Bond energy and bond length data indicates single bond character of the B-F bond
• E. All the bonds are covalent

Answer 1

Answer: (E)

$B{F}_3$ is a covalent compound. Boron has $3$ valency electrons with number $d$ -orbital. Fluorine also have number $d$-orbital with $7$ valency electrons. Thus Boron will form three covalent bonds with three fluorine atoms to complete its octate and give a stable $B{F}_3$ molecule. Hence, $B{F}_3$ is a covalent compound.
