- Amylase: This is a polysaccharide found in plants, with \( \alpha \)-1,4 and \( \alpha \)-1,6 linkages between glucose units, so the correct linkage type is \( \alpha \)-C1-C4 plant (IV).
- Cellulose: Cellulose is a polysaccharide made of \( \beta \)-1,4 linkages, commonly found in plants, so the correct linkage is \( \beta \)-C1-C4 plant (I).
- Glycogen: Glycogen is a polysaccharide found in animals, consisting of \( \alpha \)-1,4 and \( \alpha \)-1,6 linkages between glucose units, so the correct linkage is \( \alpha \)-C1-C4 \( \alpha \)-C1-C6 plant (III).
- Amylopectin: Similar to glycogen, it is found in plants and is made of \( \alpha \)-1,4 and \( \alpha \)-1,6 linkages, so the correct linkage is \( \alpha \)-C1-C4 plant (II). Thus, the correct answer is (2).
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 _________.
\[ (\mu_0 = 4\pi \times 10^{-7}\ \text{TmA}^{-1}) \]
