What will you learn in NCERT Class 11 Chemistry Chapter 13 Hydrocarbons?

The reaction of Carbon and Hydrogen forms hydrocarbons. If a hydrocarbon has single bonds, then it is saturated. And if it has multiple bonds, it is unsaturated.

Also, those hydrocarbons formed by Benzene and its derivatives are known as aromatic hydrocarbons.

Acyclic and Heterocyclic Hydrocarbons

Sometimes, hydrocarbons consist of only carbon compounds. And such compounds are known as acyclic hydrocarbon compounds. Similarly, hydrocarbon compounds having a carbon atom along with other elements are known as heterocyclic hydrocarbon compounds.


Alkanes are the simplest forms of hydrocarbons. In these types of compounds, the carbon atoms have single covalent bonds that are fully saturated by Hydrogen atoms. So, they are also known as saturated hydrocarbons. Alkanes have strong bonds and are, therefore, chemically inert. And because of this, they also are known as ‘paraffin,’ meaning that they have a lesser affinity towards chemical reactions.

Nomenclature of Alkanes

The IUPAC has guidelines for writing the structure of Hydrocarbons. As such, you can use the following steps to write the structural formula for different hydrocarbon compounds.

  1. Find the longest chain that is present in the hydrocarbon compound.
  2. Number the chain from left to right.
  3. Find the alkyl group.
  4. Write the IUPAC name.

When writing the formula, separate each number by a comma. Also, separate the numbers from the names. You don’t have to write the prefixes if you are using their alphabet substitutes.


Alkynes are those hydrocarbons with three bonds in the molecules. Acetylenes are the most important compounds in this class of hydrocarbons.

Nomenclature of Alkynes

You can give names to alkynes using the parent alkanes and add the suffix ‘-yne’ to it. You must then assign numbers to the carbon chain along with the triple bonds, starting from the end that is nearest to that bond.


There are two types of isomerism when it comes to organic compounds. The first type is structural isomerism, and the second type is geometrical isomerism. Most hydrocarbons don’t show any signs of structural isomerism. However, some compounds that have double bonds tend to show geometrical isomerism.


Hydrocarbons exhibit aromaticity if they satisfy any of the following conditions.

  1. The hydrocarbons must be cyclic and planar.
  2. Each atom in the hydrocarbon must have a parallel p orbital so that they can overlap continuously.

Physical and Chemical Properties of Benzene

Benzene is a colorless liquid and is insoluble in water. However, it is soluble in substances like alcohol, chloroform, and ether. It is also a suitable solvent for various other organic and inorganic substances like fat, resins, and Sulphur. Additionally, Benzene also undergoes Electrophilic Substitution and Addition Reactions.

Benefits of Studying from NCERT Solutions for Class 11 Chemistry Chapter 13 Hydrocarbons

Studying Chemistry from NCERT solutions come with a ton of benefits, especially for a concept like hydrocarbons. For instance, the solutions have practice questions at the end of each chapter. So, students can work on them and come out on top in not only the class 11 exams but also in the class 12 board exams and various other competitive examinations. Likewise, there are other advantages to studying from NCERT solutions.

1. Exemplar Problems

The solutions come with exemplar problems that offer a means for the students to understand the subject from a unique perspective.

2. Tips and Tricks
