UNIT 15 : ALKYL HALIDES

Alkyl Halides is a scoring conceptual chapter in MDCAT Chemistry, sitting within the 25% Chemistry allocation of your 45-question paper.

What this chapter covers:

• Nomenclature of Alkyl Halides using the IUPAC system
• Structure and reactivity of RX
• Mechanism and types of nucleophilic substitution reactions
• Mechanism and types of elimination reactions

These subtopics are almost entirely conceptual and mechanism-based rather than calculation-heavy, but they demand precise distinction between closely related pathways (SN1 versus SN2, E1 versus E2) and their governing factors, placing this chapter in the moderate range with pockets of difficulty wherever mechanisms are compared side by side.

Mastery here means being able to reason through why a given substrate, nucleophile, solvent, or condition pushes a reaction toward one mechanism over another, since MDCAT frequently tests this reasoning rather than simple recall.

Why this practice set helps:

• Covers every subtopic the PMDC curriculum identifies, plus the supporting concepts textbooks present alongside them
• Every question includes a full explanation of why the correct answer is right and why each other option is wrong
• Built to help you learn faster than passive reading, with nothing the exam may draw from left untouched

Work through this set attentively, and you build the conceptual clarity and mechanistic precision this chapter demands.
