Question

Consider the following statements about homologous series of carbon compounds:

1. All succeeding members differ by - \[\ce{CH2}\] unit.
2. Melting point and boiling point increases with increasing molecular mass.
3. The difference in molecular masses between two successive members is 16 u.
4. \[\ce{C2H2}\] and \[\ce{C3H4}\] are NOT the successive members of alkyne series.

The correct statements are:

विकल्प

• a and b

• b and c

• a and c

• c and d

Answer 1

a and b

Explanation:

In homologous series, successive members differ by a [\ce{CH2}\] unit, and their melting and boiling points rise with increasing molecular mass due to greater forces.
