Question on: JAMB Chemistry - 2014
A hydrocarbon has an empirical formula CH and a vapour density of 39. Determine its molecular formula.
[C = 12, H = 1]
A
C2H6
B
C3H8
C
C3H4
D
C6H6
Ask EduPadi AI for a detailed answer
Correct Option: D
molecular mass = 2 x vapour density
= 2 x 39 = 79
∴ Cn Hn = 78
12n + 1n = 78
13n = 78
n = (\frac{78}{13}) = 6
∴ Cn Hn = C 6H 6
