Subjective Type

(i) Arrange the following compounds in the ascending order of their basic strength and give reasons for your answer: Methylamine, Aniline, Ethylamine, Diethyl ether (ii) Name the monomers and the type of polymerization in each of the folloiwng polymers: (a) Polyester (b) Bakelite

Solution

(i) Increasing order of basic strength is as follows:
Diethylether < Aniline < methylamine < ethylamine
Reason : $$+I$$ effect of alkyl groups increases the basic strength of acids and aromatic amines are weaker bases than aliphatic amines due to delocalisation of lone pair of electrons (resonance).

(ii) (a) Monomer f Polyester: Ethylene glycol and Terephthalic acid
Type of polymerisation: Condensation Polymerisation
(b) Monomer of Bakelite: Phenol and Formaldehyde
Type of polymersation : Condensation polymerisation
