In an organic compound of molar mass 108 g mol –1 C, H and N atoms are present in 9 : 1 : 3.5 by weight. Molecular formula can be:
Text Solution
Verified by ExpertsThe correct answer is:
A
Molar mass = 108 g/mole
Element | Wt. Ratio | Wt. ratio/Atomic mass | Simple Ratio | Simple Integer ratio |
C | 9 x | = | 3 | 3 |
H | 1 x | x | 4 | 4 |
N | 3.5 x | = | 1 | 1 |
∴ C 3 H 4 N
Empirical mass = 12 × 3 + 4 + 14 = 54
n = 
= 2
∴ Molecular Formula = C 6 H 8 N 2
