The correct nomenclature for the following compound is:
- 2–carboxy–4–hydroxyhept–6–enal
- 2–carboxy–4–hydroxyhept–7–enal
- 2–formyl–4–hydroxyhept–6–enoic acid
- 2–formyl–4–hydroxyhept–7–enoic acid
The Correct Option is D
Solution and Explanation
To determine the correct IUPAC nomenclature, follow these steps:
Step 1: Identify the parent chain The parent chain consists of 7 carbon atoms (hept-) with a double bond at the 6th carbon (hept-6-en-).
Step 2: Functional groups and priority The compound contains the following functional groups: 1. A formyl group (−CHO) at the 2nd carbon, 2. A hydroxyl group (−OH) at the 4th carbon, 3. A carboxylic acid group (−COOH) at the end of the chain. The carboxylic acid group has the highest priority, so the chain is named as a derivative of ”hept-6-enoic acid”.
Step 3: Naming the substituents 1. The −CHO group is named as ”formyl” since it is a substituent and not the main functional group. 2. The −OH group is named as ”hydroxy”.
Step 4: Combine the name The substituents and parent chain are combined in the order
of their positions:
2-formyl-4-hydroxyhept-6-enoic acid.
Step 5: Validate the given options From the options provided, the correct name matches:
(3) 2-formyl-4-hydroxyhept-6-enoic acid.
Final Answer: (3)

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
