Quick Answer
This page offers comprehensive, SLO-based solved notes for Class 11 Chemistry Chapter 18: Alcohol. Aligned with the latest National Book Foundation (NBF) textbook, these notes cover solved textbook exercises, conceptual MCQs, short questions on monohydric classification, synthesis methods (alkene hydration, diols, haloalkane substitution, carbonyl/carboxylic reduction, ester hydrolysis), acidity comparisons, dehydration, esterification, relative oxidation behaviors, and the diagnostic iodoform test for Federal Board exam prep.
Chapter Overview
Chapter 18: Alcohol focuses on the chemistry of monohydric alcohols (-OH group). It begins with structural classifications into primary, secondary, and tertiary alcohols and explains how their relative physical properties correlate with intermolecular hydrogen bonding.
Syntheses of alcohols are examined, including alkene hydration, KMnO4 hydroxylation, haloalkane hydrolysis, reduction of aldehydes/ketones/carboxylic acids, and ester hydrolysis. Relative acidity trends are analyzed (primary > secondary > tertiary).
Lastly, it investigates reactions of alcohols, detailing halogenation (SOCl2, PX3, HX), dehydration to form alkenes/ethers, esterification, and differential oxidation (forming aldehydes/ketones/carboxylic acids). It concludes with the iodoform reaction to identify methyl alcohols.
