The reaction proceeds as follows: 1. The anisole (methoxybenzene) undergoes nitration with \( \text{HNO}_3/\text{H}_2\text{SO}_4 \) to form the product (A), which is 4-nitroanisole. 2. Subsequently, bromination with \( \text{Br}_2 \) (in the presence of excess iron) results in the brominated product (B), 4-bromo-2-nitroanisole.
Thus, the major products are (A) and (B) as represented in option (2).
Arrange the following compounds in increasing order of their reactivity towards \( S_N2 \) displacement: 2-Bromo-2-methylbutane, 1-Bromopentane, 2-Bromopentane.
In the following pair of halogen compounds, which compound undergoes \( S_N1 \) reaction faster and why?
Assertion (A): Aromatic primary amines cannot be prepared by Gabriel Phthalimide synthesis.
Reason (R): Aryl halides do not undergo nucleophilic substitution reaction with the anion formed by phthalimide.
The motion of an airplane is represented by the velocity-time graph as shown below. The distance covered by the airplane in the first 30.5 seconds is km.
If the domain of the function \( f(x) = \frac{1}{\sqrt{3x + 10 - x^2}} + \frac{1}{\sqrt{x + |x|}} \) is \( (a, b) \), then \( (1 + a)^2 + b^2 \) is equal to:
