Acetaldehyde i-e CH3CHO and propionaldehyde i-e-xA0-CH3CH2CHO belong from the aldehyde family hence they are homologous series-Hence- option B is the correct answer-

Which of the following pairs are members of a homologous series?CH3OCH3;CH3CH2OHCH3CHO;CH3CH2CHOCH3CH2COOH;CH3COOCH3(CH3)2CHOH;CH3CH2OH

Acetaldehyde i.e CH3CHO and propionaldehyde i.e CH3CH2CHO belong from the aldehyde family hence they are homologous series.Hence, option B is the correct answer.

Which of the following pairs are members of a homologous series?
$C H_{3} O C H_{3}; C H_{3} C H_{2} O H$
$C H_{3} C H O; C H_{3} C H_{2} C H O$
$C H_{3} C H_{2} C O O H; C H_{3} C O O C H_{3}$
$(C H_{3})_{2} C H O H; C H_{3} C H_{2} O H$

Acetaldehyde i.e $C H_{3} C H O$ and propionaldehyde i.e $C H_{3} C H_{2} C H O$ belong from the aldehyde family hence they are homologous series.
Hence, option B is the correct answer.
