(a) Interpretation: The structural formula of E and Z isomers of 2-chlorobut-2-ene should be determined. Concept introduction: Alkenes are unsaturated hydrocarbons with double covalent bond between carbon atoms. On the basis of groups bonded with the double bonded carbon atoms, alkenes can be named as E and Z-configuration. The E-configuration stands for anti-configuration whereas Z stands for same side configuration. The determination of groups must be done on the basis of their molecular mass. The group or atom with high molecular mass must be numbered as 1 and other with 2. If both 1 numbered group/atom are placed at the same side they will consider as Z-configuration and in E-configuration these groups will be at anti-position.

Solution Summary: The author explains the structural formula of E and Z isomers of 2-chlorobut-2-ene.
Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

Interpretation Introduction
(a)
Interpretation:
The structural formula of E and Z isomers of 2-chlorobut-2-ene should be determined.
Concept introduction:
Alkenes are unsaturated hydrocarbons with double covalent bond between carbon atoms. On the basis of groups bonded with the double bonded carbon atoms, alkenes can be named as E and Z-configuration. The E-configuration stands for anti-configuration whereas Z stands for same side configuration. The determination of groups must be done on the basis of their molecular mass. The group or atom with high molecular mass must be numbered as 1 and other with 2. If both 1 numbered group/atom are placed at the same side they will consider as Z-configuration and in E-configuration these groups will be at anti-position.

Interpretation:
The structural formula of E and Z isomers of 3-methylpent-2-ene should be determined.
Concept introduction:
Alkenes are unsaturated hydrocarbons with double covalent bond between carbon atoms. On the basis of groups bonded with the double bonded carbon atoms, alkenes can be named as E and Z-configuration. The E-configuration stands for anti-configuration whereas Z stands for same side configuration. The determination of groups must be done on the basis of their molecular mass. The group or atom with high molecular mass must be numbered as 1 and other with 2. If both 1 numbered group/atom are placed at the same side they will consider as Z-configuration and in E-configuration these groups will be at anti-position.
