States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn 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, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Question

The image depicts a chemical reaction illustrating the bromination of an alkylbenzene under the influence of light.

**Structure Before Reaction:**
- On the left, a benzene ring (an aromatic six-membered carbon ring with alternating double bonds) is connected to a three-carbon straight chain (propyl group).

**Reaction Conditions:**
- The reaction is carried out using bromine (\( \text{Br}_2 \)) under ultraviolet light (\( hv \)).

**Structure After Reaction:**
- On the right, the resulting structure shows the benzene ring connected to a three-carbon chain, where the terminal carbon now bears a bromine atom (\( \text{Br} \)).

**Explanation:**
This reaction is an example of photochemical free radical bromination, where the presence of light initiates the formation of bromine radicals that substitute a hydrogen atom in the alkyl chain with a bromine atom. This specific reaction features the addition of a bromine atom at the end of the propyl side chain attached to the benzene ring.
