Assertion : AlCl ₃ exists as a dimer through halogen bridged bonds. Reason : AlCl ₃ gets stability by accepting electrons from the bridged halogen.
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- C(A) is true, but (R) is false
- D(A) is false, but (R) is true
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A)
Step-by-step solution
AlCl ₃ exists as a dimer through halogen bridged bonds. In dimer Al ₂ Cl ₆ aluminium completes its octet through coordinates bond by chloine atom.
