Alcohols, phenols, and ethers happen to be basic compounds when it comes to the formation of detergents, antiseptics, and fragrances, respectively. The substitution of hydrogen atoms from a hydrocarbon by another group of atoms can certainly take place. Consequently, this results in the formation of a new compound. Formation of alcohols and phenols takes place when a hydrogen atom is replaced by –OH group. Alcohols and phenols have huge applications in daily life as well as the industry. Furthermore, the alcohol comprises one or more hydroxyl (OH) groups. Moreover, the attachment of this particular group is to the carbon atom(s). Also, ether is simply a class of organic compounds. Thus, alcohols phenols and ethers class 12 notes pdf will explain this in detail.

Introduction: Detergents, antiseptics, and scents are all made up of three basic compounds: Alcohols, Phenols, and Ethers. You've learned that replacing one or more hydrogen atoms in a hydrocarbon with another atom or a group of atoms produces a totally new chemical with entirely different properties and applications. When a hydrogen atom in an aliphatic or aromatic hydrocarbon is replaced by a –OH group, alcohols and phenols are produced. These types of chemicals have a wide range of applications in both business and everyday life. Have you ever noted that ordinary spirit, which is used to polish wooden furniture, is mostly a hydroxyl group-containing molecule called ethanol? Compounds containing –OH groups are found in the sugar we eat, the cotton we wear, and the paper we write on. Consider life without paper: no notebooks, books, newspapers, cash notes, checks, or certificates, to name a few examples. Beautiful images and engaging tales would vanish from our lives, as would publications. It'd have been a very different planet. A phenol has –OH group(s) directly attached to a carbon atom(s) of an aromatic system, whereas alcohol contains one or more hydroxyl (OH) group(s) directly attached to a carbon atom(s) of an aliphatic system (CH3OH) (C6H5OH). Another class of compounds known as 'ethers' is formed when a hydrogen atom in a hydrocarbon is replaced by an alkoxy or aryloxy group (R–O/Ar–O). For example, CH3OCH3 (dimethyl ether). List of topics according to NCERT and ...

Introduction In this unit, we shall discuss the chemistry of three classes of compounds, namely — alcohols, phenols and ethers. Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by –OH group. The subsitution of a hydrogen atom in a hydrocarbon by an alkoxy group (R–O/Ar–O) yields another class of compounds known as ‘ ethers’. Alcohols and Phenols : Classification Alcohols and phenols may be classified as mono, di, tri-or polyhydric compounds depending upon number of hydroxyl groups respectively in their structures as given below: (ii) Compounds Containing C sp 2 -OH bond These alcohols contain –OH group bonded to a carbon-carbon double bond i.e., vinylic carbon or to an aryl carbon. Ex. Vinylic alcohol : CH 2=CH–OH Nomenclature (a) Alcohols The common name of an alcohol is derived from the common name of the alkyl group and adding the word alcohol to it. Read also: Alcohols and Phenols 1. Preparation of Alcohols (i). From Alkenes (A) By acid reflux followed by hydrolysis: Alkenes react with water in the presence of acid as catalyst. The addition reaction takes place in accordance of Markovnikov’s rule. RCH=CH 2 + H 2O ⟶ RCH(OH)-CH 3 + RCH 2CH 2OH (B) By hydroboration-oxidation: Diborane reacts with alkenes to give trialkyl boranes, which is oxidised to alcohol by H2O2 in alkaline medium to give alcohol. RCH=CH 2⟶ RCH 2-CH 2-OH (ii). From hydrolysis of alkyl halides Alkyl halides upon hydrolysis yields al...

After studying this Unit, you will be able to • name alcohols, phenols and ethers according to the IUPAC system of nomenclature; • discuss the reactions involved in the preparation of alcohols from • alkenes, aldehydes, ketones and carboxylic acids; • discuss the reactions involved in the prep aration of phenols from • haloarenes, benzene sulphonic acids, diazonium salts and cumene; • discuss the reactions for preparation of ethers from (i) alcohols and (ii) alkyl halides and sodium alkoxides/aryloxides; • correlate physical properties of alcohols, phenols and ethers with their structures; • discuss chemical reactions of the three classes of compounds on the basis of their functional groups. Alcohols, phenols and ethers are the basic compounds for the formation of detergents, antiseptics and fragrances, respectively.
