hydrocarbons alkanes alkenes

When the hydrogen to carbon ratio is less than that required for alkanes in hydrocarbons, they are called as unsaturated hydrocarbons. The valencies of carbon atoms in these compounds are satisfied by the formation of a double (=) triple ( ) bonds. Compounds containi..

Hydrocarbons that contain only C-C single bonds in their molecules are called alkanes. These include open chain as well as closed chain (cyclic) hydrocarbons. For example, ethane, propane cyclopentane. Alkanes are further divided into: Open chain or acyclic..

Alkenes are unsaturated hydrocarbons containing a carbon double bond (C=C) in their molecule. They were earlier known as olefi..

These are hydrocarbons that contain at least one carbon-carbon double bond. For example, ethene, but-2-ene, but-1-en..

General formula: C n H 2 n + 2 Suffix: ane The open chain hydrocarbons are those in which carbon atoms are linked by single (or sigma) bonds to one another and also to hydrogen atoms. They are called saturated hydrocarbons as all the valencies of all the carbon atoms are sa..

Isomers are compounds having the same molecular formula but different properties due to different structural arrangement of atoms in their molecule..

No steric strain in trans-2-butene Steric strain in cis-2-butene Catalytic hydrogenation method is followed in order to obtain information about the relative stabilities of alkenes. In this method, hydrogen adds to carbon-carbon double bonds to yield the corresponding saturated alkan..

Alkenes are more reactive than alkanes due to the presence of a double bond. The carbon-carbon double bond consists of a strong bond and a weak p bond. The typical reactions of alkenes involve the breaking of this weaker p bond, viz., and formation of two sigma ( ..
