Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
Other hydrocarbon derivatives are not necessarily, such as halogenated hydrocarbons containing odd halogen molecules, containing an odd number of N atoms containing C, H. O, N four elements of the compound, their number of hydrogen atoms are odd.
The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.
The number of hydrogen atoms in the hydrocarbon must be even.
