Q. An organic compound contains 29.27% carbon, 5.69 % hydrogen and 65.04% bromine. Its empirical formula is
A) $C_{3}H_{5}Br$
B) $C_{3}H_{3}Br$
C) $C_{2}H_{4}Br_{2}$
D) $C_{3}H_{7}Br$
Explanation
(d)
$C:H:Br = \frac{2.27}{12}:\frac{5.69}{1}:\frac{65.04}{80}$
$= 2.43:5.69:0.813$
$= 3:7:1$
or empirical formula $= C_{3}H_{7}Br$
