Draw the structures of BCl 3 .NH 3 and AlCl 3 (dimer).

Question

Philoid · Accepted Answer

The Lewis acid (BCl₃) and the Lewis base (NH₃) combine together to form a compound.

The structures of the BCl₃.NH₃is:

In AlCl₃, Al has six electrons in the valence shell. Therefore, it is an electron-deficient molecule and needs two more electrons to complete its octet. The Cl atom has a lone pair of electron.

Thus, a molecule of AlCl₃ combines with the other molecule of AlCl₃ to form a dimer in order to complete its octet.
