Explanation / Answer

We can convert the bromo benzaldehyde to dueterated benzaldehyde by following four steps

(i) HOCH2CH2OH,p-toluene sulfonic acid (trace acid): For protecion of aldehydic group by formation of cyclic acetal.

(ii) Reagent C : Magnesium : it will give Grignard's reagent of the bromo benzene

(iii) Reagent X: D2O for reduction and replacent by dueterium

(iv) Reagents W: H3O+, aqueous acid (acid workup), for deprotection of aldehydic group by hydrolysis of acetal .

(v) No reagent

(vi) no reagent
