Answer:

#"Boron trifluoride"# is a molecular compound, that displays covalent bonding.

Explanation:

#BF_3# is conceived to be a weaker Lewis acid than both #BCl_3# and #BBr_3# for the reason that the lone pairs on fluorine are conceived to donate electron density to the vacant #"p-orbital"# on the boron centre. The boron nucleus is thus less electron-deficient, and this results in reduced Lewis acidity.
