The compound A on treatment with Na gives B, and with PCl5 gives C. B and C react together to give diethyl ether. A, B and C are in the order (1) C2H5Cl, C2H6 , C2H5OH (2) C2H5OH, C2H5Cl, C2H5ONa (3) C2H5OH, C2H6 , C2H5Cl (4) C2H5OH, C2H5ONa, C2H5Cl
See Alcohol have high tendency to reach with metals. So ethyl alcohol C2H5OH (A) reacts with Na first of all to form Sodium Ethanoate. C2H5ONa (B) .
Now A ie C2H5OH with PCl5 reaction gives C2H5Cl. (C)
Now B and C ie C2H5ONa and C2H5Cl together react to form diethyl ether which is true as per the question.
So the correct option as per the question is D option.
