“12th Class Chemistry Chapter 9: Hydrocarbons” deals with the vital class of organic compounds comprising only carbon and hydrogen atoms. Hydrocarbons are the backbone of chemistry, uses in the production of energy, manufacturing, and daily life. This chapter specifically deals with their classification, properties, and chemical reactions. Ace your prep with our MDCAT Quiz and free flashcards designed specifically for this topic.
Classification of Hydrocarbons
Hydrocarbons are classified into three main types depending on the type of carbon-carbon bonds they contain. Alkanes, also called saturated hydrocarbons, contain only single bonds between carbon atoms. These compounds have relatively lower reactivity; examples include methane and ethane. Alkenes are a class of unsaturated hydrocarbons that contain at least one double bond, making them more reactive. Common examples include ethene and propene. Alkynes are unsaturated hydrocarbons characterized by at least one triple bond; they are, therefore, a lot more reactive. Classic examples are ethyne and propyne.
Reactions of Hydrocarbons
Hydrocarbons exhibit a range of chemical reactions based on their structure and bonding. Combustion is a key reaction where hydrocarbons burn in oxygen to produce carbon dioxide and water, releasing energy, a process crucial for fuels. Substitution reactions are typical of alkanes, where a hydrogen atom is replaced by a halogen atom under specific conditions, such as the presence of ultraviolet light. Addition reactions, common in alkenes and alkynes, involve the breaking of double or triple bonds to add hydrogen, halogens, or water molecules. This reaction is widely utilized in industrial processes like hydrogenation to produce margarine and halogenation for chemical synthesis.
