(A) : AlCl3 exists as a dimer through halogen bridged bonds.(R) : AlCl3 gets stability by accepting electrons from the bridged halogen.

AlCl3 Dimer Structure and StabilityAssertion (A): AlCl3 exists as a dimer (Al2Cl6) through halogen (chlorine) bridged bonds.Reason (R): AlCl3 gets stability by accepting electrons from the bridged halogen atoms.AlCl3 is electron deficient and acts as a Lewis acid.Each AlCl3 molecule shares a pair of electrons from chlorine atoms with another Al atom, forming bridges to complete the octet.The dimeric structure (Al2Cl6) results in greater stability than the monomeric form.Conclusion: Both assertion and reason are correct.

AlCl₃ Dimer Structure and Stability

Assertion (A): AlCl₃ exists as a dimer (Al₂Cl₆) through halogen (chlorine) bridged bonds.

Reason (R): AlCl₃ gets stability by accepting electrons from the bridged halogen atoms.

AlCl₃ is electron deficient and acts as a Lewis acid.
Each AlCl₃ molecule shares a pair of electrons from chlorine atoms with another Al atom, forming bridges to complete the octet.
The dimeric structure (Al₂Cl₆) results in greater stability than the monomeric form.

Conclusion: Both assertion and reason are correct.
