Question

3 Which of the following is not observed in a homologous series? Give reason

1

for your choice.

a) Change in chemical properties

b) Difference in -CH2 and 14u molecular mass

c) Gradation in physical properties

d) Same functional group

​

Answer 1

b)

Because in homologous series the molecular mass is increased by 14 a.m.u as c2, c3, C4 etc

And much more which are yet to be discovered

Answer 2

Answer:

a) change in chemical properties is not observed in a homologous series, so this is right answer

Explanation:

Give reason : beacuse of same functional group, the chemical properties all same for the whole homologous series.
