**Question:**Which of the following molecules have a Hydrogen Deficiency Index (HDI, also known as degrees of unsaturation) of 2?**Molecules:**- **(I)**: Cyclopentene with a methyl group- **(II)**: Cyclohexane- **(III)**: Cyclopentadiene with a methyl group- **(IV)**: Cyclopentanone**Options:**- ○ I only- ○ II only- ○ III only- ○ I and IV**Explanation:**This question asks which of the provided molecular structures have an HDI of 2. The HDI is calculated based on the formula:\[ \text{HDI} = \frac{2n + 2 - x}{2} \]where \( n \) is the number of carbon atoms, and \( x \) is the number of hydrogen atoms and halogens. Oxygen does not affect the HDI directly, but each double bond or ring increases it by 1.
