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 alkanes higher than propane different arrangements of atoms can give a different structure. 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 R and S isomers. For example, All the substituents are different hence is is a chiral carbon and so molecule. Alkenes are the hydrocarbons which have a genral molecular formula C n H 2n . 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. (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.

Answer 1

Question

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 .
