Question

Is ever $AlC{l}_4$ possible ?

• A. True
• B. False

Answer 1

The correct option is A True

• There is dative coordination from a lone pair on a chloride ion to the vacant orbital on the aluminium ion.
  
• This gives the aluminium ion a full octet and does not change the valency rules of aluminium.
  
• Hence $AlC{l}_4$ is possible.
