two atoms of hydrogen add to the carbons in a double bond of an alkene to form an alkane.
1-nonene is an alkene, as it contains a carbon-carbon double bond.
C4H8 can refer to either an alkene or an alkane. In the case of an alkene, it would be 1-butene, while for an alkane, it would be 2-methylpropene. The distinction can be made based on the presence of a double bond in the alkene.

1-nonene is an alkene because it has a double bond between two carbon atoms in its carbon chain.
A three-carbon alkene is called propene.
hydrogenation of 2-methylpropanal gives
The alkene to alkane reaction occurs through a process called hydrogenation, where hydrogen gas is added to the alkene molecule in the presence of a catalyst, such as platinum or palladium. This results in the breaking of the double bond in the alkene, converting it into a single bond in the alkane.
Alkene
In the hydrogenation reaction of 2-pentene, a single product is formed: n-pentane. Hydrogenation involves the addition of hydrogen across the double bond of the alkene, resulting in the saturated alkane. Since 2-pentene has a symmetrical structure, it does not produce different isomers in this reaction, leading to only one primary product.
Hydrogen gas (H2) is typically used in the presence of a metal catalyst (such as platinum, palladium, or nickel) to convert an alkene to an alkane through a process known as hydrogenation. This reaction is commonly used in industrial processes to saturate double bonds in alkenes, resulting in the formation of alkanes.
Alkyne undergoes hydrogenation using a metal catalyst, such as Pd/C or Pt, and hydrogen gas to produce an alkene. During the reaction, the triple bond in the alkyne is reduced to a double bond in the alkene, with two hydrogen atoms added across the triple bond. This process allows for the conversion of alkynes to alkenes while increasing the saturation of the molecule.
Quinoline "poisons" the Lindlar catalyst, thereby enhancing its selectivity. This prevents the hydrogenation reaction from going from the alkyne to the alkane, and instead from the alkyne to the alkene.

Technically it can be described as oxidation. Technically it is an oxidation reaction, although I've never heard it described as "the oxidation of an alkane". Strange, since when an alkene is converted to an alkane by hydrogenation, we do hear it called "reduction of an alkene". Perhaps this is because the term "alkane oxidation" has been appropriated for the promising research into efficiently capturing energy by combining alkanes with oxygen at low temperatures.
Turpentine is a mixture of compounds primarily containing terpenes, which are cyclic hydrocarbons known as alkene.
... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane. --- ... known as hydrogenation.
