Question

What are likely formulas for the following molecules?

(a) $N H_{?} O H$ (b) $A l C l_{?}$ (c) $C F_{2} C l_{?}$ (d) $C H O_{?}$

Step-by-Step Solution

Verified

Answer

The chemical formula is $C H_{2} C l_{2}$ .

1Step 1: Carbon valency

Carbon belongs to group 4 A of the periodic table and has four valence electrons, due to which it can form four bonds and acquire its octet.

2Step 2: Fundamental about carbon

As carbon has four valence electrons, it needs four more electrons to make an octet. Carbon bonds to two more chlorine atoms to attain the octet configuration.

3Step 3: Chemical formula for the molecule

Thus, the possible formula of the given compound is $C H_{2} C l_{2}$ .
