Question

Boric acid is polymeric due to:
A.Its acidic nature
B.The presence of hydrogen bonds
C.Its monobasic nature
D.Its geometry

Answer 1

Hint: Polymer is a substance or material consisting of a very large chain of monomers. Monomers are structural units which repeat over and over to form polymers. Their properties depend upon their monomers.

Complete step by step solution:
Boric acid is polymeric due to its hydrogen bonding. These hydrogen bonds repeat over and over and form a long chain and which make boric acid as a polymer so answer to this question is option B that is the presence of hydrogen bonds.
Additional information: Polymers are of two types. One is a natural polymer and the other is a synthetic polymer.
Methods of making synthetic polymers are generally divided into two categories that are Chain polymerization and Step growth polymerization.
Chain growth polymerization is a technique of polymerization where unsaturated monomers are added onto the active sites of the growing polymer chain one at a time.
Step growth polymerization is a type of polymerization in which bifunctional or multifunctional monomers react to form first dimer (combination of two monomers), then trimmers (combination of three monomers), longer oligomers (a polymer whose molecules consist of relatively few repeating units) and eventually long chain polymers.
Some of the natural polymers are DNA, cellulose.

Note: Identify given compound carefully and check if there is any group present whose removal or presence can cause that compound to make a long chain. For example in this question hydrogen atom is connected to oxygen atom which makes intermolecular hydrogen bonding resulting in making a long chain polymer.
