Chemistry Ncert Solution Class 12 Chapter 11
CBSE NCERT Solutions For Class 12 Chemistry Chapter 11: If you are looking for the NCERT Solutions for Class 12 Chemistry Chapter 11, you have come to the right place. Alcohols and Phenols find wide applications in industry as well as in day-to-day life. For instance, have you ever noticed that the ordinary spirit used for polishing the wooden furniture is chiefly a compound containing hydroxyl group, ethanol? The sugar we eat, the cotton used for fabrics, the paper we use for writing, are all made up of compounds containing -OH groups.
This NCERT Class 12 Chemistry Chapter 11 explains that alcohol contains one or more hydroxyl (OH) group(s) directly attached to a carbon atom(s), of an aliphatic system (CG3OH). While a phenol contains -OH group(s) directly attached to a carbon atom(s) of an aromatic system (C6H5OH). Solving the Solutions for NCERT Class 12 Chemistry Chapter 11 will further clarify any confusion you might have on these topics. We get you the detailed NCERT Solutions for Class 12 Chemistry Chapter 11.

Chapter Description of CBSE Class 12 Chemistry Chapter 11 – Alcohols, Phenols & Ethers
The name alcohol comes from the name of the alkane from which the alcohol is derived, by substituting 'e' of alkane with the suffix 'ol'. The positions of substituents are indicated by numerals. For this, the longest carbon chain is numbered starting at the end nearest to the hydroxyl group. The positions of the -OH group and other substituents are indicated by using the numbers of carbon atoms to which these are attached. For naming polyhydric alcohols, the 'e' of alkane is retained and the ending 'ol' is added.
In CBSE NCERT Class 12 Chemistry Chapter 11, students will further know that the simplest hydroxy derivative of benzene is phenol. It is a common name and also an accepted IUPAC name. A structure of phenol involves a benzene ring, in its substituted compounds the terms ortho (1,2- disubstituted, meta (1,3- disubstituted) and para (1,4- disubstituted) are often used in the common names.

Q: Explain why propanol has a higher boiling point than of hydrocarbon, butane?
A: Propanol undergoes intermolecular H-bonding because of the presence of a −OH group. On the other hand, butane does not form H-bonding. Butane is bonded by Van der Waal's forces which is weaker than H-bond. Therefore, extra energy is required to break hydrogen bonds. For this reason, propanol's boiling point is higher than hydrocarbon butane.
Q: Alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses. Explain this fact.
A: Alcohols form hydrogen bonds with water due to the presence of −OH group since H has +δ and O has lone pair. However, hydrocarbons cannot form H-bonds with water. Therefore, alcohols are more soluble in water than hydrocarbons of comparable molecular masses.
Q: While separating a mixture of ortho and para nitrophenols by steam distillation, name the isomer which will be steam volatile. Give reason.
A: Intramolecular H-bonding is present in o-nitrophenol while in p-nitrophenol, the molecules are strongly associated due to the presence of intermolecular bonding. Hence, due to intramolecular H-bond, o-nitrophenol is steam volatile.
