Answer some questions about the compound aluminium chloride, for 10 points each:
[10e] Aluminium only has three electrons on its outer shell, and so anhydrous aluminium chloride is electron deficient due to the fact that it experiences this type of bonding, where electrons are shared between atoms.
ANSWER: covalent bonding
[10m] Due to aluminium chloride being electron deficient, two molecules of aluminium chloride will form these structures, where each molecule donates two electrons in a coordinate bond.
ANSWER: dimers
[10h] Aluminium chloride is used as a catalyst in the Gattermann-Koch reaction along with the chloride of this element. A co-catalyst of this element is used alongside a palladium catalyst in the Sonogashira coupling.
ANSWER: copper [or Cu; accept copper (II) chloride]
