Rachana, the sequence of reactions asked in the query is an example of conversion of an alkyl halide into an alcohol through the formation of GRIGNARD REAGENT.
The compounds A and B are CH3X (where X is an Halogen like Cl, Br) and CH3MgX respectively. The compound B is known as Grignard Reagent with the general chemical formula RMgX, where R is an alkyl group and X is a halogen.
The sequence can be understood as follows:--
CH3X + Mg------------(ether)------------> CH3MgX
( A ) ( B )
CH3MgX + CH3CHO---------------(acid hydrolysis)------> Propan-2-ol + Mg(X)(OH)
( B ) ( Ethanal)
Hope it solves your query.
