How is nitroethane converted into-
(a) ethyl amine, `" "` (b) N-ethylhydroxyl amine
(c) acetic acid ?
Write names and chemical formulae of monomers used in preparing Buna-N.
What are saps ? How are they prepared ?

Explanation

(a) `CH_(3)CH_(2)+NO_(2)6+[H]overset(Sn//Conc.HCI) to underset(("Ethylamine"))overset(("Nitroethane"))(CH_(3)CH_(2)NH_(2)+H_(2)O`
(b) `underset(("Nitroethane"))(C_(6)H_(5)NO_(2))+4+[H] overset(Zn+NH_(4)CI) to underset(("N-ethylydroxyl amine"))(C_(2)H_(5)NH-OH+H_(2)O)`
(c) `{:(C_(2)H_(5)NO_(2)overset("oxidation")underset(H_(2)O //H^(+)) to CH_(3)COOH),(("Nitroethane")" "("Acetic acid")):}`
(ii) Nunna-Nis a copolymer of acrylonitril and 1,3 butadiene.

(iii) Soaps are sodium or potassium salts of fatty acids.
They are formed by treating NaOH with fat or oil.
