In the given reaction scheme, P is a phenyl alkyl ether, Q is an aromatic compound; R and S are the major products.
The correct statement about S is
The correct statement about S is
It primarily inhibits noradrenaline degrading enzymes
It inhibits the synthesis of prostaglandin.
It is a narcotic drug.
It is ortho-acetylbenzoic acid.
The Correct Option is B
Approach Solution - 1
To solve this problem, we need to determine the nature and role of compound S in the provided reaction scheme. Given the options and chemical context, consider the following:
- Identify the likely transformation: Evaluate the reaction conditions and typical reactions of phenyl alkyl ether (P), aromatic compounds, and possible transformations into S.
- Focus on common pathways: Given that S could be linked to biochemical pathways involving prostaglandins, inhibition could be relevant.
- Review chemical roles: Substances that inhibit prostaglandin synthesis are often related to anti-inflammatory drugs, aligning with certain aromatic compound derivatives known to be cyclooxygenase inhibitors.
- Assess option feasibility: Compare the proposed roles of S:
- Inhibiting noradrenaline degrading enzymes is more characteristic of adrenergic antagonists.
- The narcotic implication fits alkaloid-related compounds, not typical for straightforward aromatic transformations.
- Ortho-acetylbenzoic acid differs structurally and functionally.
- Inhibition of prostaglandin synthesis aligns with anti-inflammatory properties, a plausible outcome for S.
Therefore, the correct statement is: S inhibits the synthesis of prostaglandin.
Approach Solution -2
Correct option is (B) It inhibits the synthesis of prostaglandin
S is ortho-acetoxybenzoic acid, it inhibits the synthesis of prostaglandin.

The center of a disk of radius $ r $ and mass $ m $ is attached to a spring of spring constant $ k $, inside a ring of radius $ R>r $ as shown in the figure. The other end of the spring is attached on the periphery of the ring. Both the ring and the disk are in the same vertical plane. The disk can only roll along the inside periphery of the ring, without slipping. The spring can only be stretched or compressed along the periphery of the ring, following Hooke’s law. In equilibrium, the disk is at the bottom of the ring. Assuming small displacement of the disc, the time period of oscillation of center of mass of the disk is written as $ T = \frac{2\pi}{\omega} $. The correct expression for $ \omega $ is ( $ g $ is the acceleration due to gravity):

Concepts Used:
Stoichiometry
Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers. This means that if the amounts of the separate reactants are known, then the amount of the product can be calculated. Conversely, if one reactant has a known quantity and the quantity of the products can be empirically determined, then the amount of the other reactants can also be calculated.
Stoichiometry helps us determine how much substance is needed or is present. Things that can be measured are;
- Reactants and Products mass
- Molecular weight
- Chemical equations
- Formulas
Stoichiometric Coefficient
The Stoichiometric coefficient of any given component is the number of molecules and/or formula units that participate in the reaction as written.
Mole Ratios
The mass of one mole of a substance in grams is called molar mass. The molar mass of one mole of a substance is numerically equal to the atomic/molecular formula mass.
