Solution Verified by Toppr Correct option is C) The reaction mechanism as given in the figure shows that its a electrophilic substitution reaction where :CCl 2 is the electrophile. The reaction between phenol and chloroform in the presence of aqueous NaOH is electrophilic substitution reaction Video Explanation

Answer: Treating phenol with chloroform in the presence of aqueous NaOH results in the formation of a tri-substituted phenol, also known as a trichlorophenol. The reaction is a type of halogenation reaction, where the hydrogen atoms on the phenol molecule are replaced with chlorine atoms from the chloroform molecule.

NCERT solutions for Class 12 Chemistry chapter 11 Alcohols, Phenols and Ethers start with the IUPAC nomenclature of alcohols, phenols and ethers followed by the topics:- reactions involved in the preparation of alcohols from aldehydes, ketones, alkenes and carboxylic acids and discuss reactions involved in the preparation of phenols from benzene.

Check important questions and answers for Class 12 Chemistry Board Exam 2020 from Chapter 11 - Alcohols, Phenols and Ethers. These questions are based on the latest CBSE Class 12 Chemistry Syllabus.

325 Alcohols, Phenols and Ethers Alcohols and phenols consist of two parts, an alkyl/aryl group and a hydroxyl group. The properties of alcohols and phenols are chiefly due to the hydroxyl group. The nature of alkyl and aryl groups simply modify these properties. Boiling Points The boiling points of alcohols and phenols increase with increase.

hence simpler. Therefore, let us first learn how are alcohols, phenols and ethers classified? Alcohols and phenols may be classified as mono–, di–, tri- or polyhydric compounds depending on whether they contain one, two, three or many hydroxyl groups respectively in their structures as given below: substituting the hydrogen atom of hydroxyl.

Ans: Acid catalyzed dehydration of primary carbon to ethers occurs to SN 2 reaction involving nucleophilic attack by the alcohol molecule set the protonated alcohol molecule. Under these conditions, 2° and 3° alcohols, however, give alkenes rather than ethers.

Physical Properties: (a) Boiling point of ethers are much lower than corresponding alcohols because ethers do not form intermolecular H-bonding. (b) Slightly soluble in water. 10. Chemical properties: (a) Cleavage ofC-O bond in ethers: (b) Electrophilic substitution: In this, the alkoxy group activates the aromatic ring and directs the incoming.
