In synthetic fibres, _ bonding is responsible for tensile strength.
Correct answer: B. Hydrogen
- A. Nitrogen
- B. Hydrogen
- C. Oxygen
- D. None of these
Explanation
In synthetic fibers, hydrogen bonding plays a crucial role in providing tensile strength. The hydrogen bonds form intermolecular forces that help hold the polymer chains together, enhancing the material's ability to withstand pulling forces. While nitrogen and oxygen can be present in the polymer structure, they are not primarily responsible for tensile strength. Therefore, hydrogen is the correct answer, as it directly contributes to the strength through its bonding.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
