List I List II
(Compounds) (Reactions)
(a)CH3(CH2)3NH2(i) Alkaline hydrolysis
(b)CH3C≡CH(ii) With KOH(alcohol) and CHCl3 produces bad smell
(c)CH3CH2COOCH3(iii) Gives white ppt. with ammoniacal AgNO3
(d)CH3CH(OH)CH3(iv) With Lucas reagent cloudiness appears after 5 minutes

a-(ii), b - (i), c - (iv), d- (iii)

a - (iii), b - (ii), c - (i), d - (iv)

Solution:

(a)CH3(CH2)3NH2 with KOH (alcohol) and CHCl3 produces bad smell. The bad smell is due to the formation of isocyanide.
CH3CH2CH2CH2NH2 + KOH(alc) --→ CHCl3 + CH3CH2CH2CH2NC + 3KCl + 3H2O
(b)CH3C≡CH Gives white ppt. of silver salt of propene with ammoniacal AgNO3
CH3C≡CH + Amm.AgNO3 → CH3C≡CAg + HNO3
white ppt
(c)CH3CH2COOCH3 an ester on alkaline hydrolysis gives a mixture of methanol and propanoic acid.
CH3CH2COOCH3 + NaOH Heat → CH3CH2COONa + CH3OH
(d)CH3CH(OH)CH3 reacts with Lucas reagent and cloudiness appears after 5 minutes .
CH3CH(OH)CH3 + HCl anh.ZnCl2 → CH3−CH(Cl)−CH3 + H2O
This indicates a secondary alcohol.
