Question

how to write different positions of isomers of unsaturated hydrocarbons

Answer 1

TO WRITE THE DIFFERENT POSITION OF ISOMERS OF UNSATURATED HYDROCARBON:

1) First draw the different carbon chains keeping in mind the condition for isomerism

2) If it is an alkene draw the first isomer always by drawing a double bond between C1 and C2 if it is an alkaline draw the first isomer always drawing a triple bond betweenC1 and C2 .

3) The next isomers will be drawn by drawing the same Chain and changing the positions of the double bond and the triple Bond in alkenes and alkynes respectively

4) Complete the tetravalency of carbon by forming single covalent bonds with hydrogen check that the molecular formula of the isomer should be same

Answer 2

• Ethane , with a single bond between the two carbons, adopts a two-tetrahedron shape (one tetrahedron about each carbon). Importantly, rotation occurs freely about the carbon-carbon bond.
• In contrast, ethene with a double bond between the two carbons, is planer (all of its atoms lie in the same plane). Furthermore, rotation about the carbon-carbon double bond is restricted. This is a general feature of carbon-carbon double bonds, so anytime you see one of these in a molecule, remember that the portion of the molecule containing the double bond will be planar and unable to rotate.
• Finally, ethyne , with a triple bond between the two carbons, is both planar and linear. As with the double bond, rotation is completely restricted about the carbon-carbon triple bond.
