Is functional group carbon Counted?
The highest priority functional group is the double bond, and the carbon chain must be numbered such that this functional group is given the lowest number carbon.

Is the functional group with a carbonyl group at the end of a carbon chain?
Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. For example, H2C=O is methanal, more commonly called formaldehyde. Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is by default position #1, and therefore defines the numbering direction.
What is parent carbon chain?
The longest continuous chain of connected carbon atoms in a hydrocarbon is called as the parent chain.
How do you classify functional groups?
Functional groups are usually classified as hydrophobic or hydrophilic depending on their charge or polarity. An example of a hydrophobic group is the non-polar methane molecule.
Is a carbon carbon multiple bond considered a functional group?
Both carbon-carbon and carbon-hydrogen sigma bonds are single strong, nonpolar covalent bonds that are normally the least reactive bonds in organic molecules. Alkane sequences form the inert framework of most organic compounds. For this reason, alkanes are not formally considered a functional group.

How many carbons are in the longest chain in the structure?
seven C atoms
The longest continuous carbon chain has seven C atoms, so this molecule is named as a heptane. There is a two-carbon substituent on the main chain, which is an ethyl group….Example 2.

What functional group ends with?
Other Functional Groups
| Name | Official Name of Example (Common Name) Formal Name Ending |
|---|---|
| carboxylic acid | ethanoic acid (acetic acid) -oic acid endings |
| ester | methyl ethanoate (methyl acetate) -oate endings |
| amide | ethanamide (acetamide) -amide endlings |
| alkyl halide | chloromethane |
What two functional groups can be found at the end of a carbon chain?
The aldehydes and ketones contain what is known as the carbonyl group. A carbonyl group is a carbon atom double bonded to an oxygen atom \begin{align*}(\mathrm{C}=\mathrm{O})\end{align*}, and the carbon is also bounded to two other atoms or groups. In an aldehyde, the carbonyl group is always on an end carbon.
What is a parent functional group?
Parent structures bearing one or more functional groups that are not specifically denoted by a suffix are called functional parents. Names of parent structures are used in IUPAC nomenclature as basis for systematic names. A parent hydride is a parent structure with one or more hydrogen atoms.
