Strength Of Intermolecular Forces

Answer

Step by step text solution for Strength Of Intermolecular Forces by CHEMISTRY experts to help you in doubts & scoring excellent marks in Class 11 exams.

Intermolecular forces are

forces of attraction and repulsion between atoms or molecules

electrostatic forces between two oppositely charged ions

forces that hold the atoms of a molecular together

both (2) and (3)

Assertion : Polymerides are bust used as fiber because of high tensile strength. Reason : Strong intermolecular forces (like hydrogen bonding within polyamides) lead to close tracking of chains and increase the crystalline character, hence, provide high tensile strength to polymers.

Assertion and reason both are correct statement but reason does not explain assertion.

Assertion and reason both are correct statements and reason explains the assertion.

Both assertion and reason are wrong statement.
