Vedclass · Answer

$BCl_3$

$B+C{{l}_{2}}	o \underset{\begin{smallmatrix} 
 [does\,not\,dimerise\,due\,to\, \ 
 (p\pi -p\pi )back\,bonding] 
\end{smallmatrix}}{\mathop{BC{{l}_{3}}}}\,\xrightarrow{N{{H}_{3}}}$

$BCl_3$ is electron deficient but it does not form dimer like $Al,Ga$ or $In$ because its electron deficiency is complemented by the formation of co-ordinate bond between lone pair of electron of chlorine and empty unhybridized $p-$ orbital of boron forming $p\pi -p\pi$ bonding.

A group $13$ element $'X'$ reacts with chlorine gas to produce a compound $XCl_3. XCl_3$ is electron deficient and easily reacts with $NH_3$ to form $Cl_3X \leftarrow NH_3$ adduct, however, $XCl_3$ does not dimerize. $X$ is
