why is the formation of a condensation polymer impossible in these cases ?
A) ethanoic acid + NH2CH2CH2CH2CH2NH2
B) ethanoic acid+CH3CH2NH2
C) HOOC-CH2-COOH + CH3CH2NH2
The formation of a condensation polymer involves a reaction between two or more monomers, resulting in the formation of a polymer and the release of a small molecule such as water. In these cases, the formation of a condensation polymer is not possible due to the absence of necessary functional groups or reactants.
A) In the case of ethanoic acid (CH3COOH) and NH2CH2CH2CH2CH2NH2 (a five-carbon diamine), the reaction would not occur because neither ethanoic acid nor the diamine contains reactive groups capable of undergoing a condensation reaction. Both compounds lack functional groups like hydroxyl (-OH) or amino (-NH2) groups that can react with each other to form polymers.
B) Similarly, ethanoic acid (CH3COOH) and CH3CH2NH2 (ethylamine) also lack the necessary functional groups to undergo a condensation reaction. Ethanoic acid only has a carboxyl group (-COOH), whereas ethylamine only possesses an amino group (-NH2). Without the appropriate reactive functional groups, these molecules cannot form a condensation polymer.
C) HOOC-CH2-COOH (oxalic acid) and CH3CH2NH2 (ethylamine) also lack the necessary functional groups for condensation polymer formation. Oxalic acid has two carboxyl groups (-COOH), which can potentially undergo a condensation reaction, but ethylamine does not have any functional groups capable of reacting with the carboxyl groups. Therefore, no polymerization can occur in this case.
In summary, the absence of appropriate functional groups or reactive units in the given compounds prevents the formation of a condensation polymer. To form a condensation polymer, two or more reactants need to possess complementary functional groups that can react with each other and eliminate a small molecule like water during the polymerization process.
