... Condensation polymers are those in which the molecular formula of the repeat unit of the polymer chain lacks certain atoms present in the monomer from which it is formed(or to which it can be degraded) for example, a polyester is formed by typical condensation reaction between bifunctional monomers, ...

... Ans. i. a. Nitro (-NO2) group is an electron withdrawing whereas methoxy (-OCH3) group is electron releasing in nature. o-nitrophenol produces H+ ions easily but methoxyphenol does not. This is because o-nitrophenoxide ion is stabilised due to resonance. This is not true with o-methoxyphenoxide ion. ...
