Interpretation:
The systematic name of the compound
Concept Introduction:
Rules for naming compound:
- 1) The carbon atoms in the longest chain have to be counted.
- 2) The substituents and multiple bonds have to be identified and counted and the suffix “-ene” is added.
- 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end that contains the double bond.
Rules for naming compound:
- 1) The carbon atoms in the longest chain have to be counted.
- 2) The substituents and multiple bonds have to be identified and counted and the suffix “-yne” is added.
- 3) The backbone carbon atoms have to be numbered by assigning the lowest number from the starting end that contains the double bond.
Geometrical isomers: In geometrical isomers, atoms have different arrangements on either side of a double bond above or below the ring of a cycloalkane or cycloalkane. If the atoms are present on the same side of the double bond, then it is cis-isomer and if they are present on the opposite side of the double bond, then it is trans-isomer.
