Both $(A)$ and $(R)$ are true and $(R)$ is the correct explanation of $(A)$

Vedclass · Answer

(A) $AlCl_3$ is an electron-deficient compound with only $6$ electrons in the valence shell of $Al$.To complete its octet,it forms a dimer $Al_2Cl_6$ where two chlorine atoms act as bridges.Each bridging chlorine atom donates a lone pair of electrons to the vacant $p$-orbital of the $Al$ atom of the other $AlCl_3$ unit,forming a coordinate bond.Thus,both the assertion and the reason are true,and the reason correctly explains the stability of the dimer.

Assertion $(A)$: $AlCl_3$ exists as a dimer through halogen bridged bonds.
Reason $(R)$: $AlCl_3$ gets stability by accepting electrons from the bridged halogen.
