The product formed from the following reaction sequence is
The Correct Option is D
Approach Solution - 1
To determine the product of the given reaction sequence, we need to carefully analyze the type of reactions involved and the structural changes they impart to the starting material. Without explicit details on the reaction sequence in text form, we'll follow a generic approach for common reaction types typically encountered at this level:
- Step 1: Identify the Functional Groups - Examine the structure of the starting material to identify key functional groups susceptible to chemical reactions, such as alcohol, carboxylic acid, alkene, etc.
- Step 2: Determine Reaction Type - Look for common reactions like oxidation, reduction, substitution, or addition that typically apply to identified functional groups. For example, an alkene might undergo addition reactions, while alcohols might be oxidized to carbonyl compounds.
- Step 3: Predict Structural Changes - Based on the reaction type, predict how the structure of the starting material is altered. Adjust your skeletal formula or structure accordingly by adding or removing atoms/groups as dictated by the reaction mechanisms.
- Step 4: Analyze Reaction Conditions - Conditions such as temperature, pressure, and catalysts can influence the direction or type of reaction, e.g., acidic conditions may promote different pathways compared to basic conditions.
- Step 5: Match with Product Options - Compare your predicted product structure against provided options to select the correct answer.
After analyzing and following this logical approach, the correct product for the given reaction sequence corresponds with the option:

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)

Concepts Used:
Preparation of Amines
- Reduction of nitro compounds: Nitro compounds are reduced to amines by reduction with metals in an acidic medium or by passing them through hydrogen gas in the presence of finely divided nickel, palladium, or platinum.
- Ammonolysis of alkyl halides: Alkyl benzyl halide undergoes a nucleophilic substitution reaction while reacting with an ethanolic solution of ammonia where the halogen atom is replaced by an amino group and this process of splitting of the C-X bond by an ammonia molecule is called ammonolysis.
- Reduction of Nitriles: On reduction of nitriles with lithium or aluminum hydride or catalytic hydrogenation are used.
- Reduction of amides: On reduction, the amides with lithium aluminum hydride yield amines.
- Gabriel phthalimide synthesis: Gabriel synthesis is used to prepare primary amines. Phthalimidewhen treated with ethanolic potassium hydroxide, forms potassium salt of phthalimide which when heated with alkyl halide followed by alkaline hydrolysis leads to the formation of the corresponding primary amine.
- Hoffmann bromamide degradation reaction: In the Hoffmann bromamide degradation reaction, the transfer of an alkyl or aryl group takes place from the carbonyl carbon of the amide to the nitrogen atom. The amine so formed, therefore, contains one carbon less than that present in the initial amine.
