Quick Answer
This page provides solved notes, multiple-choice questions (MCQs), short-answer questions, and detailed long-answer questions for 10th Class Chemistry Chapter 9: Hydrocarbons under the Federal Board (FBISE) curriculum. All material is aligned with the latest National Book Foundation (NBF) textbook for the 2026-2027 academic session, emphasizing Student Learning Outcomes (SLO) such as alkanes vs alkenes vs alkynes, preparation of alkenes (cracking, dehydration of alcohols, dehydrohalogenation), reactions with halogens/KMnO4, bromine test distinction, fossil fuels (coal, gas, petroleum), and fractional distillation of crude oil.
Chapter Overview
Chapter 9, 'Hydrocarbons', covers the study of organic compounds composed entirely of carbon and hydrogen. It distinguishes between saturated hydrocarbons (alkanes) and unsaturated hydrocarbons (alkenes and alkynes).
The chapter outlines the specific chemical pathways for preparing alkenes, including the catalytic cracking of long-chain alkanes, dehydration of alcohols, and dehydrohalogenation of halogenoalkanes. It also explains their chemical reactions with halogens and cold alkaline potassium permanganate (KMnO4).
Lastly, students learn how to differentiate saturated from unsaturated compounds using the bromine water test (demonstrated through butter vs vegetable oil reactions). It also addresses the origins, separation, and extraction of fossil fuels (coal, natural gas, petroleum) via fractional distillation of crude oil.
