Match List-I with List-II: List-I
- (A) Aniline from aniline-water mixture: This is typically done using steam distillation (IV).
- (B) Glycerol from spent-lye in soap industry: This is done using fractional distillation (II).
- (C) Different fractions of crude oil: This is done using distillation at reduced pressure (III).
- (D) Chloroform-Aniline mixture: This is separated using simple distillation (I).
Thus, the correct answer is (2).
The correct increasing order of stability of the complexes based on \( \Delta \) value is:
| List I (Molecule) | List II (Number and types of bond/s between two carbon atoms) | ||
| A. | ethane | I. | one σ-bond and two π-bonds |
| B. | ethene | II. | two π-bonds |
| C. | carbon molecule, C2 | III. | one σ-bonds |
| D. | ethyne | IV. | one σ-bond and one π-bond |

A square loop of sides \( a = 1 \, {m} \) is held normally in front of a point charge \( q = 1 \, {C} \). The flux of the electric field through the shaded region is \( \frac{5}{p} \times \frac{1}{\varepsilon_0} \, {Nm}^2/{C} \), where the value of \( p \) is:
