Question:

Why does aluminum in the aluminum chloride not have a full octet yet it's a viable molecule?

The aluminum in aluminum chloride forms 3 bonds with the chlorides, it is obviously missing a pair of electrons or bond.

Answer:

Try some fruitIt's good for you, and it'll satisfy your sweet toothThe white parts of an orange is fiber, and the skin of an apple is fiber packed too.
That's the reason why aluminium chloride (AlCl3) is only stable at high temperatureAt low temperature, two molecules of aluminium chloride will join together to form a dimer (Al2Cl6) so that it can achieve octetThis is possible because chlorine atom from each molecule will donate a pair of electrons to form the dative bondsCl Cl Cl / / Al Al / / Cl Cl Cl ( The two dative bonds are between the two Al and the central Cl ( upper and lower each)
