Match List I with List II:
| LIST I (Type) | LIST II (Name) |
| (P) Antifertility drugs | (A) Norethindrone |
| (Q) Antihistamines | (B) Seldane |
| (R) Tranquilizers | (C) Meprobamate |
| (S) Antibiotics | (D) Penicillin |
Choose the correct answer from the options given below:
Match drug types with their functions:
• Antifertility drug: Contraceptive hormones.
• Tranquilizer: Reduces anxiety.
• Antihistamine: Treats allergies.
• Antibiotic: Treats bacterial infections.
P → (A), Q → (B), R → (C), S → (D)
P → (A), Q → (C), R → (B), S → (D)
P → (D), Q → (C), R → (B), S → (A)
P → (A), Q → (D), R → (B), S → (C)
The correct matches are:
• Antifertility drug: Norethindrone is a synthetic hormone used in contraceptive pills.
• Tranquilizer: Meprobamate is used as a sedative or tranquilizer.
• Antihistamine: Seldane is an antihistamine used to treat allergies.
• Antibiotic: Ampicillin is a broad-spectrum antibiotic used to treat bacterial infections.
Thus, the correct matching is:
A-I, B-II, C-III, D-IV.
Given below are two statements:
Statement I: D-(+)-glucose + D-(+)-fructose $\xrightarrow{H_2O}$ sucrose sucrose $\xrightarrow{\text{Hydrolysis}}$ D-(+)-glucose + D-(+)-fructose
Statement II: Invert sugar is formed during sucrose hydrolysis.
In the light of the above statements, choose the correct answer from the options given below -
Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).

In the first configuration (1) as shown in the figure, four identical charges \( q_0 \) are kept at the corners A, B, C and D of square of side length \( a \). In the second configuration (2), the same charges are shifted to mid points C, E, H, and F of the square. If \( K = \frac{1}{4\pi \epsilon_0} \), the difference between the potential energies of configuration (2) and (1) is given by:
The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
