is a non-planar compound, therefore it is not aromatic.
So, the correct option is (C).
The product of hydrolysis of propyne in the presence of 1% \( HgSO_4 \) and 40% \( H_2SO_4 \) is ___________.
The structures of major products A , B and C in the following reaction are sequence

Uniform magnetic fields of different strengths $ B_1 $ and $ B_2 $, both normal to the plane of the paper, exist as shown in the figure. A charged particle of mass $ m $ and charge $ q $, at the interface at an instant, moves into region 2 with velocity $ v $ and returns to the interface. It continues to move into region 1 and finally reaches the interface. What is the displacement of the particle during this movement along the interface?
Consider the velocity of the particle to be normal to the magnetic field and  $ B_2 > B_1 $.
For a given reaction \( R \rightarrow P \), \( t_{1/2} \) is related to \([A_0]\) as given in the table. Given: \( \log 2 = 0.30 \). Which of the following is true? 
 
| \([A]\) (mol/L) | \(t_{1/2}\) (min) | 
|---|---|
| 0.100 | 200 | 
| 0.025 | 100 | 
A. The order of the reaction is \( \frac{1}{2} \). 
B. If \( [A_0] \) is 1 M, then \( t_{1/2} \) is \( 200/\sqrt{10} \) min. 
C. The order of the reaction changes to 1 if the concentration of reactant changes from 0.100 M to 0.500 M. 
D. \( t_{1/2} \) is 800 min for \( [A_0] = 1.6 \) M. 
Aromatic hydrocarbons, sometimes known as arenes, are aromatic organic molecules made up entirely of carbon and hydrogen. In aromatic compounds a benzene ring which is named after the simple aromatic chemical benzene, or a phenyl group when part of a larger structure, is the configuration of six carbon atoms.

This reaction involves the replacement of one substituent on the ring of an aromatic hydrocarbon, commonly a hydrogen atom, by a different substituent group.
The common types of aromatic substitution reactions are:
In these types of reactions, the coupling of two fragments that have a radical nature is achieved with the help of a metal catalyst
