Match List - I with List - II:

Choose the correct answer from the options given below:
We will match the structure in List I with its corresponding IUPAC name in List II.
- (A) The structure corresponds to 4-Methylpent-1-ene. This is because the longest chain is 5 carbons, with a methyl group at position 4 and a double bond at position 1.
- (B) The structure corresponds to 4,4-Dimethylheptane. The central carbon is attached to two methyl groups, and the longest chain has 7 carbon atoms.
- (C) The structure corresponds to 3-Ethyl-5-methylheptane. It is a heptane chain with an ethyl group at position 3 and a methyl group at position 5.
- (D) The structure corresponds to 2-Methyl-1,3-pentadiene. It is a pentadiene chain with a methyl group at position 2 and double bonds at positions 1 and 3. Thus, the correct matching is (A)-(I)}, (B)-(III), (C)-(II), (D)-(IV).





Consider the following reaction of benzene. the percentage of oxygen is _______ %. (Nearest integer) 
A substance 'X' (1.5 g) dissolved in 150 g of a solvent 'Y' (molar mass = 300 g mol$^{-1}$) led to an elevation of the boiling point by 0.5 K. The relative lowering in the vapour pressure of the solvent 'Y' is $____________ \(\times 10^{-2}\). (nearest integer)
[Given : $K_{b}$ of the solvent = 5.0 K kg mol$^{-1}$]
Assume the solution to be dilute and no association or dissociation of X takes place in solution.
Inductance of a coil with \(10^4\) turns is \(10\,\text{mH}\) and it is connected to a DC source of \(10\,\text{V}\) with internal resistance \(10\,\Omega\). The energy density in the inductor when the current reaches \( \left(\frac{1}{e}\right) \) of its maximum value is \[ \alpha \pi \times \frac{1}{e^2}\ \text{J m}^{-3}. \] The value of \( \alpha \) is _________.
\[ (\mu_0 = 4\pi \times 10^{-7}\ \text{TmA}^{-1}) \]
