In which case butane is formed

Options

A. `2C_(2)H_(5)-Cl + Na`
B. `C_(2)H_(5)COOH + Na_(2)CO_(3)`
C. `CH_(2) = CH - CH_(3) + H_(2)SO_(4)`
D. None of these

Answer

A

Explanation

This is called Wurtz reaction.
`C_2H_5COOH + Na_(2)CO_(3) rarr underset("sodium propanoate")(2C_2H_5COONa) + CO_2 + H_(2)O`
`CH_(3) - CH = CH_(2) + H^(+)HSO_(4)^(-) rarr underset("isopropyl hydrogen sulphate")(CH_3-underset(HSO_4)underset(|)(CH)-CH_3)`
