Alcohol phenol ether ncert

Classification Of Alcohol, Phenol and Ether Alcohol, phenol, ether are classes of organic compounds which find wide usage in a broad range of industries as well as for domestic purposes. • Alcohol is formed when a saturated carbon atom is bonded to a hydroxyl (-OH) group. • Phenol is formed when a hydrogen atom in a benzene molecule is replaced by the -OH group. • Ether is formed when an oxygen atom is connected to two alkyl or aryl groups. CLASSIFICATION OF ALCOHOL, PHENOL AND ETHER In this section, we will discuss how alcohols, phenol’s and ethers are classified. Table Of Contents • • • • Classification of Alcohol Depending on the number of hydroxyl groups attached, alcohols can be classified into three types. • Monohydric alcohols: They contain one -OH group. Example, CH 3CH 2-OH • Dihydric alcohols: They contain two -OH groups. Example, 1,2-Ethandiol. • Trihydric alcohols: They contain three -OH groups. Example 1,2,3-Propantriol. Depending on the number of • Primary alcohols: One carbon atom is directly attached. • Secondary alcohols: Two carbon atoms are directly attached. • Tertiary alcohols: Three carbon atoms are directly attached. Classification of Phenol Depending on the number of hydroxyl groups attached, phenols can be classified into three types. • Monohydric phenols: They contain one -OH group. • Dihydric phenols: They contain two -OH groups. They may be ortho-, meta- or para- derivative. • Trihydric phenols: They contain three -OH groups. Classification o...

The NCERT Class 12 Chemistry chapter 11 notes are very important for the exam. Students will study about the preparation, characteristics, and reactivity of alcohols, phenols, and ethers in this chapter. This chapter addresses some of the most fundamental topics in organic chemistry, as well as their industrial applications. Table of contents NCERT Class 12 Chemistry chapter 11. NCERT Class 12 Chemistry chapter 11 notes provide a brief synopsis of the chapter for quick preparation of Also, students can refer, • NCERT Notes Class 12 Chemistry • • NCERT Class 12 Chemistry Chapter 11 Notes NCERT Class 12 Chemistry Chapter 11 Notes: Topic 1 Classification of Alcohols and Phenols • Alcohols and phenols are classed as monohydric, dihydric, trihydric, or polyhydric depending on how many hydroxyl groups they have in their molecules: one, two, three, or many, respectively • Alcohols with the OH group connected to a primary, secondary, or tertiary carbon atom are known as primary (1°), secondary (2°), and tertiary (3°) alcohols. • Allylic alcohol is made up of an -OH group attached to an sp 3 hybridized carbon next to a carbon carbon double bond, whereas benzylic alcohol is made up of an -OH group attached to an sp 3 hybridized carbon close to an aromatic ring. Alcohols having -OH group bonded to carbon-carbon double bond is called vinylic alcohol NCERT Class 12 Chemistry Chapter 11 Notes: Topic 2 Structure of Alcohols and Phenols Alcohols have sp 3 hybridized oxygen atoms and hybri...

To get carboxylic acids directly from alcohol, which of the following oxidising agents is used? a) Alkaline KMnO 4 b) Aqueous KMnO 4 c) Acidified KMnO 4 d) Anhydrous CrO 3 Answer: c Explanation: Strong oxidizers, such as acidified potassium permanganate or acidified potassium dichromate, convert alcohol to carboxylic acid immediately. Using CrO 3 as the oxidising agent in an anhydrous media, however, only aldehyde can be produced. 2. When phenol reacts with bromine water, what is the result? a) Brown liquid b) Colourless gas c) White precipitate d) No reaction Answer: c Explanation: When phenol is treated with bromine water, a white precipitate is formed, which is 2,4,6-Tribromophenol. 3. The Lucas test was carried out on three different compounds: A, B, and C. Compounds A and B were turbid at ambient temperature, while compound...
