. An organic compound contains H = 4.07%, Cl = 71.65% chlorine and remaining carbon


An organic compound contains H = 4.07%, Cl = 71.65% chlorine and remaining carbon. Its molar mass = 98.96. Find,

(a) Empirical formula, and

(b) Molecular formula

 

Best Answer

Element % at. Mass atomic ratio simple ratio

Cl71.6535.5Mass atomic 1

H4.071Mass atomic 2

C24.2812Mass atomic 1

 

(a) its empirical formula = CH2Cl

(b) empirical formula mass = 49.5

Since, molecular mass = 98.96

so, molecular formula = (CH2Cl)2 = C2H4Cl2
