Question

Answer 1

CONCEPT:

Difference between intermolecular and intramolecular forces:

Sr.No	Intermolecular forces	Intramolecular forces
1.	The forces that bind individual molecules in a substance are called intermolecular forces.	Forces that hold atoms in a molecule are called intramolecular forces.
2.	The intermolecular forces are much weaker than intramolecular forces.	The intramolecular forces are much stronger than intermolecular forces.
3.	Intermolecular forces determine the state of matter (solid/liquid/gas) and their physical properties such as melting/ boiling point etc.	Intramolecular forces determine the chemical behavior of a substance.
4.	The strength of intermolecular forces is more for solid than liquid and then for gas.	The strength is relative to the electronegativity of the 2 atoms in the molecule.
5.	Intermolecular forces are attractive forces.	Intramolecular forces are chemical bonds.

EXPLANATION:

So from the above discussion, it's clear that as intramolecular forces hold the molecule from inside and molecules are present in all solid, liquid, gas.

The correct option is 1.
