Question

As the molecular mass increases in any homologous series of carbon compounds

a- The melting and boiling point increases

b- The melting and boiling point decreases

c- The melting point increases and boiling point decreases

d- The melting point decreases and boiling point increases


​

Answer 1

Answer:

The number of C atoms in homologous series increases gradually. Van der Waal's increases as the molecules get bigger. Hence, the melting and boiling points of the members of homologous series increase gradually because their molecular masses increase.
