Which one of the following statements is wrong?
Anisole reacts with Ethanoyl chloride / anhydrous $\mathrm{AlCl}_3$ in $\mathrm{CS}_2$ to form 4-Methoxyacetophenone in larger amount
Isopropyl methyl ether reacts with Conc. HI to produce isopropyl alcohol and methyl iodide by $\mathrm{S}_{\mathrm{N}} 2$ mechanism
Tert. butyl methyl ether reacts with Conc. HI on heating to form 2-lodo-2-methylpropane and Methanol by $\mathrm{S}_{\mathrm{N}} 1$ mechanism
Anisole is prepared by reaction between Bromobenzene and Sodium methoxide

Consider a Galvanic cell in which the following reactions occurs: $\mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{Ag}^{+}(\mathrm{aq}) \rightarrow \mathrm{Fe}^{3+}(\mathrm{aq})+\mathrm{Ag}(\mathrm{s})$. What is the standard potential of the cell? Given: $\mathrm{E}^0\left(\mathrm{Ag}^{+} / \mathrm{Ag}\right)=\mathrm{aV} \quad \mathrm{E}^0\left(\mathrm{Fe}^{2+} / \mathrm{Fe}\right)=\mathrm{bV} \quad \& \quad \mathrm{E}^0\left(\mathrm{Fe}^{3+} / \mathrm{Fe}\right)=\mathrm{cV}$
$(a+2 b-3 c) V$
$(a+b+2 c) V$
$(a-2 c+b) V$
$(a+c-2 b) V$
