30sSPS2c - Q8
NH3 is nitrogen trihydride (ammonia) and BF3 is boron trifluoride. What is the name for AlCl3 and why?
Monoaluminium trichloride - There is only one aluminum, and it needs the prefix "mono-".
Aluminum chloride - It does not have the prefix "tri-" since it is ionic.
Aluminum chloride - Ionic compounds do not get a prefix on the first name if there is only one of that element.
Aluminum trichloride - It has the prefix "tri-" since it has the same ratio as the other compounds.
