Distinguishing
← Back to Organic Chemistry Problem-Solving Approach
Approach:
Spot the difference: FG or structure?
- FG: Use a test specific to the FG present in only one of the two compounds.
- Structure: Most of the time → Iodoform or selective oxidation
| Example: Work in Progress |
Note:
- In general, there is no FG test for esters and amides. They need to be hydrolysed into their respective acid/alcohol/amine before testing.
- Exception: 1⁰ amides produce NH3 on hydrolysis
| Example: Work in Progress |
