$BF_3$ exists as a dimer.

Vedclass · Answer

(C) The correct statement is that $BF_3$ does not exist as a dimer because the small size of the $B$ atom cannot accommodate four large $F$ atoms around it due to steric hindrance. Other boron trihalides like $BCl_3$,$BBr_3$,and $BI_3$ do not form dimers either,but $BF_3$ is specifically known for its monomeric nature. $BF_3$ is a strong Lewis acid due to its electron-deficient nature. Ammonal is indeed a mixture of aluminium powder and ammonium nitrate used as an explosive. $BF_3$ is a covalent molecule and does not ionize in its liquid state,hence it is a poor conductor of electricity.
