Vedclass · Answer

(B) Molecular bromine $(Br_2)$ reacts with $3$ moles of molecular fluorine $(F_2)$ to produce $2$ moles of $BrF_3$.$BrF_3$ is an interhalogen compound.The chemical reaction is:$Br_{2(g)} + 3F_{2(g)} \longrightarrow 2BrF_{3(g)}$In $BrF_3$,the central bromine atom has $7$ valence electrons. It forms $3$ covalent bonds with $3$ fluorine atoms,using $3$ electrons.Remaining electrons = $7 - 3 = 4$ electrons,which form $2$ lone pairs.Thus,the total number of lone pairs at the central bromine atom is $2$.

Molecular bromine on reaction with three moles of molecular fluorine produces an interhalogen compound. The total number of lone pairs at the central halogen atom is
