The IUPAC name of the following compound is :
Show Hint
- 2-nitro-4-hydroxymethyl-5-amino benzaldehyde
- 3-amino-4-hydroxymethyl-5-nitro benzaldehyde
- 4-amino-2-formyl-5-hydroxymehtyl nitrobenzene
- 5-amino-4-hydroxymethyl-2-nitro benzaldehyde
The Correct Option is D
Solution and Explanation
The aldehyde is the principal group, so the parent is benzaldehyde with C1 bearing CHO.
Numbering through the \(\mathrm{NO_2}\) carbon gives \(\mathrm{NO_2}\) at C2, \(\mathrm{CH_2OH}\) at C4, \(\mathrm{NH_2}\) at C5: locant set {2,4,5}.
Numbering the other way gives {3,4,6}; {2,4,5} is lower.
Prefixes in alphabetical order: amino, hydroxymethyl, nitro.
Name: 5-amino-4-hydroxymethyl-2-nitrobenzaldehyde.
Answer: (4) 5-amino-4-hydroxymethyl-2-nitro benzaldehyde

Top JEE Main Questions
- 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:
