Alkyl Halides consists of Alkyl and Halogen groups. They have a different nomenclature. They are prepared by alcohol. In Alkyl Halides, there are two main components for their Reactivity. They are C-X bond energy and C-X bond polarity. They undergo Substitution Reactions. In Alkyl Halides, there are two types of reactions. The first one is Nucleophilic Substitution Reaction in which Sn2 and Sn1 occur. The Second one is Beta-Elimination Reaction in which E2 and E1 occur. The most important one about Alkyl Halides is Grignard Reagent. It is the derivative of Alkyl Halides. Grignard Reagents reacts with different compounds and forms a new product. So, this is a brief intro to this chapter. Check out the important MCQs of this chapter given below.<\/p>\n<h2 style=\"text-align: center;\">2nd Year Chemistry Alkyl Halides MCQs<\/h2>\n<p><img decoding=\"async\" loading=\"lazy\"
