Percentage composition of an organic compounds is as follows: C = 10.06, H = 0.84, Cl = 89.10. Which of the following corresponds to its molecular formula if the vapour density is 60.0 .

Options

A. `CH_(2)Cl`
B. `CHCl_(3)`
C. `CH_(3)Cl`
D. None of these

Answer

B

Explanation

Empirical formula = `CHCl_(3)`
Empirical formula mass `= 12 + 1 + 3(35.5) = 120`
Molecular mass = `2 xx 60 = 120`
Molecular formula = `CHCl_(3)`
