Application +4 | -1
The compound A on treatment with Na gives B\mathrm{B}, and with PCI5\mathrm{PC}{\mathrm{I}_\mathrm{5}} gives C . B\mathrm{C}\,\mathrm{.}\,\mathrm{B} and C\mathrm{C} react together to give diethyl
ether. A,  B  and  C\mathrm{A,}\,\,\mathrm{B}\,\,\mathrm{and}\,\,\mathrm{C} are in the order.
View answer and explanation
Correct option: A
C2H5OH,   C2H5 ONa,  C2H4 = 5 CI{\mathrm{C}_\mathrm{2}}{\mathrm{H}_\mathrm{5}}\mathrm{OH,}\,\,\,{\mathrm{C}_\mathrm{2}}{\mathrm{H}_\mathrm{5}}\,\mathrm{ONa,}\,\,{\mathrm{C}_\mathrm{2}}{\mathrm{H}_{\mathrm{4}\,\mathrm{ = }\,\mathrm{5}}}\,\mathrm{CI}
Option A (C2H5OH   C2H5 ONa C2H4 = 5 CI{\mathrm{C}_\mathrm{2}}{\mathrm{H}_\mathrm{5}}\mathrm{OH}\,\,\,{\mathrm{C}_\mathrm{2}}{\mathrm{H}_\mathrm{5}}\,\mathrm{ONa}\,{\mathrm{C}_\mathrm{2}}{\mathrm{H}_{\mathrm{4}\,\mathrm{ = }\,\mathrm{5}}}\,\mathrm{CI}) is correct because ethanol reacts with Na to form sodium ethoxide and with PCl5 to form chloroethane, which then react to form diethyl ether via Williamson ether synthesis.
