The reaction
`2C_(2)H_(5)Ohoverset(Conc.H_(2)SO_(4))underset(140^(@)C)(rarr)(C_(2)H_(5))_(2)O+H_(2)O`
is an example of

A

an elimination reaction `(E_(2))`

B

a nucleophiic substitution `(S_(N)l)` reaction

C

a nucleophilic substitution `(S_(N)2)`reaction

D

an electrophilic substitution `(S_(E)2)` reaction

Text Solution

Verified by Experts

The correct Answer is:
C

Step `2` is an `S_(N)2` displacement of `H_(2)O` by the nucleophile `CH_(3)CH_(2)OH`. Formation of alkenes is minimized by the continous addition of `C_(2)H_(5)OH` to the warmed alcohol-sulphuric acid mixture.
