The molecule that has minimum /no role in the formation of photochemical smog, is :
Show Hint
- \(\mathrm{CH_2{=}O}\)
- \(\mathrm{O_3}\)
- \(\mathrm{N_2}\)
- \(\mathrm{NO}\)
The Correct Option is C
Solution and Explanation
\(\mathrm{NO_2 \xrightarrow{h\nu} NO + O}\); \(\mathrm{O + O_2 \rightarrow O_3}\); O3 reacts with NO and hydrocarbons to give HCHO (formaldehyde), acrolein and PAN.
So NO, O3 and CH2=O all participate (as reactant, oxidant or product). N2 is chemically inert at ordinary temperatures and has essentially no role.
Answer: (3) \(\mathrm{N_2}\)

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:
