Concept introduction:
Alkenes are the hydrocarbons which have a genral molecular formula
(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.

- Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomersarrow_forwardDraw a chiral alkene with the formula C6H12.arrow_forwardHow many isomers, both structural and geometric, have the molecular formula C5H12?arrow_forward
- Describe structural isomerism and the different types that exist. With the aid of diagrams use the molecular formulae C5H12 and C5H10 to explain structural isomerism in aliphatic alkanes and alkenesarrow_forwardGive the molecular formula of a hydrocarbon containingsix carbon atoms that is (a) a cyclic alkane, (b) a cyclicalkene, (c) a linear alkyne, (d) an aromatic hydrocarbon.arrow_forwardThere are 11 structures (ignoring stereoisomerism) with the formula C4H8O that have no carbon branches. Draw the structures and identify the functional groups in each.arrow_forward
