प्रश्न
You are given the following molecular formulae of some hydrocarbons:
C5H8; C7H14; C6H6; C5H10; C7H12; C6H12
Which three formulae can represent cyclic hydrocarbons?
उत्तर
C7H14, C5H10, C6H12 are the three molecular formulae which represent cyclic hydrocarbons, as they correspond to the general formula CnH2n, where n is the number of carbon atoms in its one molecule. The closed chains of cyclic hydrocarbons contain as many carbon atoms as denoted by their molecular formulae. Therefore, a cyclic hydrocarbon containing 7 carbon atoms will be a closed cycloheptane, a cyclic hydrocarbon with 5 carbon atoms will form a pentagonal ring called cyclopentane and a cyclic hydrocarbon with 6 carbon atoms will form a cyclohexane.
