Transcribed Image Text:**Question 2**
How many signals would be present in the \( ^1\text{HNMR} \)?
*Diagram: Chemical structure of an ester with a methyl group and an ethyl group attached to an oxygen atom.*
- O
- R1: Methyl group (CH3)
- R2: Ethyl group (CH2CH3)
**Options:**
- none of the above
- 6
- 4
- 5
**Explanation:**
When analyzing the molecule's structure, each unique hydrogen environment contributes a separate signal to the \( ^1\text{HNMR} \) spectrum. Consider the methyl (CH3) and methylene (CH2) groups to determine how many distinct hydrogen signals the molecule would display in an NMR analysis.
