When a substance changes from a solid to a liquid or from a liquid to a gas whether intermolecular forces changes or not has to be analyzed and explained. The reason for a substance to undergo phase change has to be identified. Concept introduction: Matter exists in three distinct physical forms – solid, liquid and gas. There are two types of interactions present in matter – intramolecular meaning, “within the molecule” and intermolecular meaning “between the molecules”. Intramolecular force refers to the type of bonding that holds the atoms or ions together to form a stable molecule. Intermolecular force refers to the type of interaction that exists between the so formed molecules by bonding. The nature and strength of the intermolecular forces varies in solids, liquids and gases. The classification of intermolecular force is summarized as follows – Figure 1 There are three types of intermolecular forces - London dispersion forces, dipole-dipole forces and hydrogen bonding. These forces are collectively known as Van der Waals forces . London dispersion forces exist in non-polar covalent compounds . Dipole-dipole forces present in polar covalent compounds . Hydrogen bonding is formed in polar covalent compounds containing Hydrogen and other high electronegativity like Fluorine, Oxygen or Nitrogen . It is relatively the strongest one.

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Interpretation Introduction
Interpretation:
When a substance changes from a solid to a liquid or from a liquid to a gas whether intermolecular forces changes or not has to be analyzed and explained.
The reason for a substance to undergo phase change has to be identified.
Concept introduction:
Matter exists in three distinct physical forms – solid, liquid and gas. There are two types of interactions present in matter – intramolecular meaning, “within the molecule” and intermolecular meaning “between the molecules”.
Intramolecular force refers to the type of bonding that holds the atoms or ions together to form a stable molecule. Intermolecular force refers to the type of interaction that exists between the so formed molecules by bonding.
The nature and strength of the intermolecular forces varies in solids, liquids and gases. The classification of intermolecular force is summarized as follows –
Figure 1
There are three types of intermolecular forces - London dispersion forces, dipole-dipole forces and hydrogen bonding. These forces are collectively known as Van der Waals forces. London dispersion forces exist in non-polar covalent compounds. Dipole-dipole forces present in polar covalent compounds. Hydrogen bonding is formed in polar covalent compounds containing Hydrogen and other high electronegativity like Fluorine, Oxygen or Nitrogen. It is relatively the strongest one.

Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the products.
In the drawing area below, draw the skeletal ("line") structures of the missing organic products X and Y. You may draw the structures in any arrangement that
you like, so long as they aren't touching.
