(i) The valency of carbon is 4 and that of chlorine is 1. What will be the formula of carbon tetrachloride?
(ii) The valency of an element X is 1 and that of oxygen is 2. What will be the formula of the compound formed by the combination of element X with oxygen?
i. Given:
Valency of carbon is 4
Valency of chlorine is 1
By applying criss-cross method:
Formula: CCl4
Thus, the formula for carbon tetrachloride is CCl4.
ii. Given:
Valency of element X is 1
Valency of oxygen is 2
By applying criss-cross method:
Formula: X2O
