Question

The general formula of the organic compounds ‘A’, ‘B’ and ‘C’ is CnH2n. Their boiling points are – 162 ºC, – 42.2 ºC and – 0.5 ºC respectively. Based on this information answer the following : (a) Which type of compounds ‘A’, ‘B’ and ‘C’ are and why ? (b) Which of these has maximum number of carbon atoms in the molecule and why ? (c) Write the name and structural formula of the second member of this series.

Answer 1

● Answers :-
a) Compounds with general formula CnH2n must be alkenes (most probably) or cycloalkanes (rarely).

b) Boiling point increases with molecular mass which depends on number of C atoms. As boiling point B is highest, it would have maximum number of C atoms.

c) Second member of alkene series is propene. Structural formula of propene is CH3-CH=CH2 .
