Interpretation: It should be detrmined the correct statement by considering the following compound .
Concept introduction: Structural Isomers are the structure of a molecule with same molecular formula but have different arrangements of bonds and atoms. For a single molecular formula of
A chiral carbon is the carbon atom which is substituted to four different groups. Due to presence of chiral carbon a molecule become chiral and it gives optical isomers also that is
All the substituents are different hence is is a chiral carbon and so molecule.
(1) 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.
(2) 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.
