Question

Plse someone do help me in this question ​

Answer 1

a series of compound have same functional group and halogen with the difference of - CH2

and difference of 14 U mass

homologous series - ch3 , c2h5 , c3h7 etc .

its physical properties As the molecular mass increases in any homologous series, a gradation in physical properties is seen. This is because the melting points and boiling points increase with increasing molecular mass. Other physical properties such as solubility in a particular solvent also show a similar gradation.

i hope it will help you
