Draw cis and trans isomers of the following compounds. Also write their IUPAC names :
(i) CHCl = CHCl
( ii) `C_(2)H_(5)"CC"H_(3)="CC"H_(3)C_(2)H_(5)`

Draw geometrical (or cis-and trans-) isomers of the following structures and give their IUPAC names. (i) C_(2)H_(5)C CH_(3)=C CH_(3)C_(2)H_(5) (ii) CH_(3)CH_(2)CH=CHCH_(2)CH_(3) Strategy: An isomer in which two identical atoms (or groups) lie on the same sides of the double bond is called as cis isomer whereas an isomers in which identical atoms ( or groups) lie on the opposite sides of the double bond is called a trans isomer.
