What is the name of the compound with the formula al(ch3coo)3 ?

             Aluminium Acetate

Explanation:

                   Aluminium Acetate is made up of Aluminium and Acetic Acid. The chemical formula of Aluminium Acetate can be opened into its components as,

                                   Al(H₃CCOO)₃    →     Al⁺³  +  3 H₃CCOO⁻

It means Aluminium Acetate is made up of one Aluminium Cation and three Acetate Anions.

Nomenclature:

                      Ionic compounds are named as the Positive specie is named first (in our case Aluminium) and the negative part is named secondly (in our case Acetate).

Name of Acetate Ion:

                           Carboxylic acids are weak acids. On donation of proton carboxylic acids are converted into Carboxylate ions as,

              R--COOH    →    R--COO⁻  +  H⁺    (Carboxylic acid into Carboxylate)

Examples:

              H₃C--COOH    →    H₃--COO⁻  +  H⁺    (Acitic acid into Acetate)

    H₅C₂--COOH    →    H₅C₂--COO⁻  +  H⁺    (Propanoic acid into Propanoate)

you need to stop taking that class
