Answer:
True
Step-by-step explanation:
Hydrocarbons are classified in to Unsaturated and Saturated classes.
Saturated Compounds:
These are those organic compounds which has only single bonds between the carbon atoms. For example, Alkane are the saturated compounds. The Carbon atom in these compounds are Sp³ hybridized and the geometry along carbon atom is tetrahedral.
Unsaturated Compounds:
These are those organic compounds which has either a double bond (alkenes) or triple bonds (alkynes) between the carbon atoms. The Carbon atom in alkenes is Sp² hybridized and the geometry along carbon atom is triangular while, The Carbon atom in alkynes is Sp hybridized and the geometry along carbon atom is linear.
The reaction in which alkanes (saturated) compounds are converted into alkenes are called as dehydrogenation reactions while, the reactions in which the unsaturated compounds (alkene and alkyne) are converted into saturated compounds are called as hydrogenation or reduction reactions. Hence, we can conclude that the dehydrogenation of alkanes results in the formation of unsaturated compounds.
