A hydrocarbon X which decolorizes bromine water but has no action on ammoniacal silver trioxonitrate (V) solution was found to have a molar mass of 58 g mol(^{-1})
(a) Deduce the molecular formula of X. (H = 1, C = 12)
(b) Write the structures of two isomers of X.
Explanation
(a) The test carried out shows the hydrocarbon x is an alkene. The smallest number of the family is ethene (C(_2H_4))
If ((C+2H_4)_x = 56)
i.e. (28)x = 56
x = (frac{56}{28}) = 2
2((C_2H_4)) = C(_4)H(_8)
(b)
