Which of the following statements is correct?

The structural feature in carbonyl compound for Aldol condensation

Calculate the emf of the following cell at 298 K if \(E_{\text {Cell }}^{\circ}=1.10 \mathrm{~V}:\)
\(\mathrm{Ni}(\mathrm{s})+2 \mathrm{Ag}^{+}(0.2 \mathrm{M}) \rightarrow \mathrm{Ni}^{2+}(0.04 \mathrm{M})+2 \mathrm{Ag}(\mathrm{s})\)

Which solutions will have the highest boiling point?

Read the following passage carefully and answer the given questions. During anaerobic sludge digestion, bacteria produce a mixture of gases such as methane, hydrogen sulphide and carbon dioxide. These gases form biogas and can be used as source of energy as it is inflammable. The bioactive molecule, cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungus Trichoderma polysporum. You must have noticed that bottled fruit juices bought from the market are clearer as compared to those made at home. This is because the bottled juices are clarified by the use of pectinases and proteases. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents. It acts by competitively inhibiting the enzyme responsible for synthesis of cholesterol. The BOD test measures the rate of uptake of oxygen by microorganisms in a sample of water and thus, indirectly, BOD is a measure of the organic matter present in the water.
BOD is a measure of-

(Assume that the density of water is \(1 ~ g ~ m L ~ m L ^{ 1 }\) )

Three charges, +Q, q and +Q are placed with q at mid point of the line joining the other two charges. For the system of charges to be in equilibrium, the value of q is

hen a mixture of \(K _2 Cr _2 O _7\) and NaCl is warmed with concentrated \(H _2 SO _4\), red vapours of \((A)\) are evolved, which turn NaOH yellowish due to formation of compound (B). A and B respectively are:
