A gaseous mixture of ethane, ethene, and ethyne is passed into an ammoniacal `AgNO_3` solution. The gas that escapes from the solution is expected to contain

Options

A. ethene
B. ethane and ethyne
C. ethene end ethyne
D. ethane and ethene

Answer

D

Explanation

Only ethyne with acidic H atoms reacts with ammoniacal `AgNO_3`:
`HC-=Choverset(Ag(NH_3)_2^(+)OH^(-))tounderset("White ppt.")(AgC-=Cag)`
Thus, ethane and etheneescape from the solution.
