Assertion : $\mathrm{AlCl}_3$ exists as a dimer through halogen bridged bonds.
Reason : $\mathrm{AlCl}_3$ gets stability by accepting electrons from the bridged halogen.
Both (A) and (R) are true and (R) is the correct explanation of (A)
Both (A) and (R) are true but (R) is not the correct explanation of (A)
(A) is true, but (R) is false
(A) is false, but (R) is true
Solution
$\mathrm{AlCl}_3$ exists as a dimer through halogen bridged bonds. In dimer $\mathrm{Al}_2 \mathrm{Cl}_6$ aluminium completes its octet through coordinates bond by chloine atom.
