प्रश्न
You are given the following molecular formulae of some hydrocarbons:
C5H8; C7H14; C6H6; C5H10; C7H12; C6H12
Which formula represent cyclohexane as well as hexene?
उत्तर
C6H12 is the molecular formula which represents cyclohexane as well as hexene. The molecular formula for both hexene and cyclohexane is the same in which there are 6 carbon atoms. However, their structure differs, as in a cyclic compound, the carbon atoms form closed chains while hexene has an open chain structure.
