Topics Covered in NCERT Solutions for Class 11 Chemistry Chapter 13- Hydrocarbons
CBSE Class 11 NCERT Solutions for Chemistry Chapter 13 Hydrocarbons is an essential chapter from the academic perspective. This chapter holds a significant weightage in your internal as well as final exams. In this chapter, in addition to all important concepts taught, remembering Nomenclature, Isomerism, Preparation, Properties and Conformations remain the most important elements. Here are some of the most important terms of the chapter that will help you brush up your concepts.
Hydrocarbons are organic compounds that consist of Carbon and Hydrogen only.
Hydrocarbons are classified into two types- open-chain compounds and cyclic compounds. Examples of hydrocarbons include Alkanes, Alkenes and Alkynes, etc.
Alkanes are open-chain compounds that contain carbon-carbon single bonds. These hydrocarbons don’t react with acids, bases or other regents under the normal conditions. Alkanes are prepared by soda-lime, from the hydrogenation of Alkenes and Alkynes, reduction of alkyl halides, Kolbe’s electrolysis, Clemmensen’s reduction, compounds containing oxygen, Wolff-Kishnerts reduction, Corey-House synthesis and by Wurtz reaction. Alkanes exhibit the conformational, position and chain isomerism.
Chemical Properties of Alkanes
- Controlled Oxidation.
- Reaction with Steam.
- Halogenation: Bromination, Iodination and Chlorination.
Alkenes are the hydrocarbons that have the presence of a double bond between the carbon atoms (C=C). Alkenes are also called olefins. The isomerism of Alkenes consists of the structural and geometrical isomerism. Alkenes can be prepared in various ways namely, from Alkyl Halide, Alkynes, Alcohols by Acidic Dehydrogenation and Vicinal dihalides.
Chemical Properties of Alkenes
- Addition of Sulphuric Acid.
- Addition of Water.
- Addition of Halogens.
- Substitution Reactions.
These are hydrocarbons that are unsaturated in nature. The position of triple bond is determined by ozone in Alkynes. Alkynes can be prepared from vicinal dihalides, calcium carbide and tetrahalides.
Chemical Properties of Alkynes
- Electrophilic addition reactions.
- Acidic character of alkyne.
- Addition of halogens.
- Addition of water.
- Cyclic polymerisation.
- Linear polymerization.
Benzene is a highly unsaturated compound. According to Kekule, the cyclic planar structure of benzene is six carbons with the alternate double and alternate single bonds. The preparation of benzene includes heating phenol with zinc dust, bypassing acetylene through the red-hot tube at 500 degrees Celsius and by the decarboxylation. The chemical properties of benzene include electrophilic substitution reaction and addition reaction.
The electrophilic substitution reaction includes nitration, halogenation, sulphonation and Friedel-crafts alkylation reaction. Ensure preparing all the equations of the preparations in addition to the IUPAC names as they are crucial from the examination’s perspective.
