Reducing smog is a mixture of :
Show Hint
- Smoke, fog and \(\mathrm{O_3}\)
- Smoke, fog and \(\mathrm{N_2O_3}\)
- Smoke, fog and \(\mathrm{CH_2=CH-CHO}\)
- Smoke, fog and \(\mathrm{SO_2}\)
The Correct Option is D
Solution and Explanation
Photochemical (oxidising) smog contains \(O_3\), PAN, acrolein (\(CH_2=CHCHO\)), \(NO_x\) and hydrocarbons, so options (1) and (3) belong to it.
Answer: (4) Smoke, fog and \(SO_2\)

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:
