Alkyl Halides MDCAT Quiz; Alkyl Halides represent one of the most basic classes of organic compounds, having an alkyl group and a halogen atom—fluorine, chlorine, bromine, or iodine—bonded together. They are essential in organic chemistry, and quite often, a number of chemical reactions include them as well. Alkyl halides are categorized into primary, secondary, or tertiary according to the number of carbon atoms bonded to the carbon holding the halogen. Alkyl halides undergo nucleophilic substitution and elimination reactions; they are also very important in the synthesis of a large number of chemicals, including pharmaceuticals and agrochemicals. MDCAT students need to understand their structure, properties, and reactivity since they commonly occur in exam questions about organic reactions.
