Three different compounds with the formula C2H2Cl2 are known.(a) Two of these compounds are geometric isomers. Draw their structures.(b) The third compound is a structural isomer of the other two. Draw its structure.

(a)

Interpretation Introduction

Interpretation:

The two geometrical isomers has to be drwan with molecular formula C2H2Cl2.

Concept Introduction:

Alkenes are the hydrocarbons which have a genral molecular formula CnH2n. Alkenes are consist of double bond (one pi bond) due to which they are known as unsaturated hydrocarbons. Alkenes can show two type of isomerism,(1) Geometrical Isomerism (2) Structural Isomerism.

Geometrical Isomerism: This type of isomerism in case of alkenes is known as cis-trans isomerism. When two same group or have similar priority present opposite side of double bond then isomer is known as trans isomer, and if both are present same side of the double bond then isomer is called as cis isomer.

Explanation

The geometrical isomers of the given alkene are drawn below.

The geometrical isomers of the given compound are cis and trans form of the alkene...

(b)

Interpretation Introduction

Interpretation:

The structural isomer has to be drwan with molecular formula C2H2Cl2.

Concept Introduction:

Alkenes are the hydrocarbons which have a genral molecular formula CnH2n. Alkenes are consist of double bond (one pi bond) due to which they are known as unsaturated hydrocarbons. Alkenes can show two type of isomerism,(1) Geometrical Isomerism (2) Structural Isomerism.

Structural Isomerism: Structural Isomers are the structure of a molecule with same molecular formula but have different arrangements of bonds and atoms and position of double bond also changes from more substituted to less substituted or vice-versa.
