Question

a) Two compounds AB,, AC, are given. The oxidation state of C is-1. What will be the
oxidation state of B?


b) Write the molecular formula of the compound formed by B when it combines with
aluminium (AI) having oxidation state +3.​

Answer 1

Answer:

(a) -1 ; (b) AlB3

Explanation:

the compounds AB and AC are neutral.

hence, if C has os -1, then A has +1

and if A has +1, then B will have -1.

Al is os +3

so, to counteract the 3 positive charge, three negative charges are required.

therefore, Compound formed between Al and B will have a molecular formula of AlB3
