Interpretation:
IUPAC name for the product obtained on hydrogenation of given
Concept Introduction:
Addition of hydrogen molecule to an unsaturated bond present in hydrocarbon is known as hydrogenation. During hydrogenation, the unsaturated bond present is broken and a carbon‑hydrogen bond is formed. Hydrogenation can be accomplished by use of metal catalyst such as platinum, nickel, or palladium.
Balanced equation is the one where the atoms of the same kind are equal on both sides of the chemical equation.
IUPAC rules for naming
A common nomenclature of naming organic compounds has been developed by IUPAC. By usage of this nomenclature or rules, memorizing of names of organic compounds is not necessary.
There are about five rules that has to be followed for naming an alkane and they are,
- The longest continuous carbon chain in the compound has to be identified. This is known as parent compound. From this the parent name is obtained. Suffix “–ane” (for alkane) is added at the end of the prefix which gives information about the number of carbon atoms.
- Numbering has to be done so that the lowest number is given to the first group that is encountered in the parent chain.
- Naming and numbering has to be given for each atom or group that is attached to the parent chain. Numbering has to be done in a way that substituents get the least numbering.
- If the same substitution is present in the parent chain more than once, a separate prefix is added which tells about the number of times the substituent occurs. Prefixes used are di-, tri-, tetra-, penta- etc.
- Name of the substituents has to be placed in an alphabetical order before the parent compound name.

- Identify the missing organic reactants in the following reaction: X + Y H+ two steps Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H2O) are not shown. In the drawing area below, draw the skeletal ("line") structures of the missing organic reactants X and Y.
