Which of the following products is formed in the given reaction?
The acidic strength of following compounds are in the order
Consider the following cell reaction.
$$\begin{aligned} & 2 \mathrm{Fe}(s)+\mathrm{O}_2(g)+4 \mathrm{H}^{+}(a q) \longrightarrow \\ & 2 \mathrm{Fe}^{2+}(a q)+2 \mathrm{H}_2 \mathrm{O}(l), E^{\circ}=1.67 \mathrm{~V} \\ \end{aligned}$$
At $$[\mathrm{Fe}^{2+}]=10^{-5} \mathrm{M}, {\mathrm{P}}{ }_2=3 \mathrm{~atm}$$ and $$\mathrm{pH}=2.5$$, the cell potential at $$25^{\circ} \mathrm{C}$$ is
In a set of reactions acetophenone gave a product $$B$$. Identify the product $$B$$.
$$\mathrm{C}_6 \mathrm{H}_5 \mathrm{COCH}_3 \xrightarrow{\mathrm{C}_6 \mathrm{H}_5 \mathrm{MgBr}} A \xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} B$$
