Classes Of Functional Groups
Organic Chemistry deals mostly with carbon and hydrogens, also called hydrocarbons, but those groups which replace hydrogen and bonds with carbon to give a characteristic nature, unique of their own, to the hydrocarbon they are attached to, are called functional groups. All the compounds belonging to a functional group undergo reactions in a similar pattern and are known to have similar physical and chemical properties.
Characteristics Of Functional Groups
In organic chemistry, we encounter a number of special substituent groups which are attached to the hydrocarbon backbone. These groups impart certain characteristics to the molecule of which it is a part of and thus, become the highlight of that particular molecule.
IUPAC Nomenclature
In Chemistry, IUPAC stands for International Union of Pure and Applied Chemistry which suggested a systematic naming approach for the organic and inorganic compounds, as in the beginning stage of nomenclature one single chemical compound was named in many ways by which lead to confusion. The need for this approach aroused as the number of chemical compounds newly discovered were increasing (approximately 32 million compounds) and the basic concept of nomenclature i.e. the trivial nomenclature and the derived system of nomenclature failed to overcome the challenge. It is an important task to name a chemical compound systematically and unambiguously which reduces lots of confusion about the newly reported compounds.

**Question 11 of 24**
**Prompt:**
> Provide the correct IUPAC name for the compound shown here.
**Structure:**
The diagram in the prompt represents a hydrocarbon molecule with the following configuration:
```
H3C
|
H3C—C=C—CH3
|
CH2—CH2—CH3
```
**Interactive Selection:**
Below the molecular diagram, there are various clickable options for constructing the IUPAC name of the compound:
1. Prefix Options:
- (E)-
- (Z)-
- sec-
- tert-
- cyclo-
2. Number Options:
- 2-
- 3-
- 3,4-
- 4-
- 4,5-
- 5-
3. Multiplicative Prefix Options:
- di
- tri
4. Root Name Options:
- meth
- eth
- prop
- but
- hex
- hept
5. Suffix Options (not shown in this specific image but commonly needed for complete naming):
- ane
- ene
- yne
To identify the correct IUPAC name of the compound, follow these steps:
1. **Identify the Longest Carbon Chain:**
- The longest carbon chain incorporating the double bond is five carbon atoms long.
2. **Number the Chain:**
- Number the chain from the end nearest to the double bond to give the double bond the lowest possible number.
- There are substituents (methyl groups) at positions 2 and 4.
3. **Assign Numbers to Substituents:**
- Methyl groups are attached to the 2nd and 4th carbons.
4. **Construct the Name:**
- Prefix: two methyl groups → "2,4-dimethyl"
- Base name with double bond in the chain: pentene with the double bond starting at position 3 → "3-pentene"
- Combining: "2,4-dimethyl-3-pentene"
**Correct IUPAC Name:**
> 2,4-dimethyl-3-pentene
