1.

(a) Complete the following reactions: (i) CH-=CH+H_(2)O underset(HgSO_(4), 333K)overset(Dil. H_(2)SO_(4))to ? (ii) CH_(3)CHO+HCN to ? (iii) HCHO+NaOH to ? (b) How will you prepare RCOOH from? (i) Alcohol (ii) Nitrile.

Answer»

Solution :(a) (i) `CH-=CH+H_(2)O underset(HgSO_(4), 333K)overset(Dil. H_(2)SO_(4))to CH_(3)-CHO`
(ii)
(iii) `2HCHO+underset((50%))(NaOH) to CH_(3)OH +HCOONa`
(b) (i) `R-CH_(2)OH underset(KMnO_(4) // OH^(-))overset((O))to RCHO underset(KMnO_(4) // OH^(-))overset((O))to RCOOH`
(ii) `R-CN+2H_(2)O underset(Delta)overset(Dil. HCl)to RCOOH+NH_(3)`
