Question

8. write the dimeric structure of Alcl3​

Answer 1

Answer:

The change in structure is related to the lower density of the liquid phase (1.78 g/cm3) vs solidaluminium trichloride (2.48 g/cm3). Al2Cl6 dimersare also found in the vapour phase. At higher temperatures, the Al2Cl6 dimers dissociate into trigonal planar AlCl3, which is structurally analogous to BF3.
