Answer : The molecular of the compound is, C_2H_4Br_2

Explanation :

The Empirical formula = CH_2Br

The empirical formula weight = 1(12) + 2(1) + 1(80) = 94 gram/eq

Now we have to calculate the molecular formula of the compound.

Formula used :

$n=\frac{\text{Molecular formula}}{\text{Empirical formula weight}}$

where,

n = valency factor

Now put all the given values in this formula, we get:

$n=\frac{188}{94}=2$

Molecular formula = (CH_2Br)_n=(CH_2Br)_2=C_2H_4Br_2

Therefore, the molecular of the compound is, C_2H_4Br_2
