Polyamides are polymers that form from the reaction between a. a carboxylic acid and an amine b. two alkenes c. an amine and an alcohol d. two carboxylic acids

Polyamides are polymers where they are made of repeating units that are connected together by amide bonds.
Most commonly known example for a polyamide is proteins. Proteins are made of amino acids. Amino acid consists of both a carboxylic acid and amine group. When the carboxylic group of one bonds to the amine group of the adjacent amino acid, it removes a water molecule during the bond formation. The bond formed is a called an amide bond.
The units forming the polyamide are linked together by amide bonds.
Correct answer is A. Reaction is formed between Carboxylic acid and amine

Igonna be honest i dunno that one srry
