Answer to Question #112132 in General Chemistry for Philip

Question

One mole of hydrocarbon contains 48g of carbon. If it's vapour density is 28, the hydrocarbon is
a. An alkane
b.An alkene
c.An alkyne
d.Aromatic

Answer 1

1mole=48g of carbon.

vapor density is 28

$Molecular mass = \text{2 vapor density.}$ = 14

n=48/14=3

n carbon=4

=C₄H₃ (d.Aromatic)
