To be more precise, these tend to be electrophilic substitutions. However, it does take part in substitution reactions. Therefore, benzene doesn’t readily take part in reactions that involve breaking the ring, such as addition reactions. It takes a lot of energy to disrupt the delocalisation. This ring of delocalisation is relatively strong and stable because it spreads the charge of the electrons over a greater area. How does benzene react?Īs we explored above, benzene contains delocalised pi electrons found in a ring. If you want a more in-depth explanation about the structure and bonding within benzene, check out Aromatic Chemistry and Benzene Structure. Overlapping pi orbitals in benzene form a ring of delocalisation The electrons can move freely within this area - we say that they are delocalised. We find these electrons in an area formed by overlapping pi orbitals above and below the benzene ring. This means that each carbon atom has a spare valence electron. Aromatic molecules are also known as arenes.Įach carbon atom within benzene is bonded to two other carbon atoms and one hydrogen atom. So, let's get started! What is benzene?īefore we go any further, let’s first remind ourselves about benzene.īenzene is an aromatic hydrocarbon with the molecular formula. You'll also be able to write an equation for the combustion of benzene. We'll also look at other reactions that benzene can participate in, such as combustion and hydrogenation.īy the end of this article, you'll know what an electrophile is, how to draw the mechanisms for electrophilic substitution reactions involving benzene, and why benzene doesn't participate in addition reactions. We'll then explore specific reactions such as nitration, chlorination, and Friedel-Crafts acylation. The first type of reaction we'll look at is electrophilic substitution, which involves adding an electrophile to the benzene ring. TNT also has a methyl group attached to the benzene ring.īut how do we go from a flat benzene molecule to the complex structure of TNT? To do that, we need to understand the reactions of benzene in organic chemistry. The hydrogen and carbon atoms in TNT come from the benzene ring, while the nitrogen and oxygen atoms come from three nitrate groups attached to the ring. The main component of TNT is benzene, which is a type of hydrocarbon. Because of these properties, it's used in many different situations, from mining to military tasks in wet environments. TNT has a low melting point, which means it can be used as a liquid, and it doesn't dissolve in water. When it detonates, a wave of pressure triggers a reaction that produces a lot of gas and heat. TNT, or trinitrotoluene, is a highly explosive substance. Have you ever wondered what happens when TNT explodes? Let's take a closer look.
