1.

In which case butane is formedA. `2C_2H_5-Cl+Na`B. `C_2H_5COOH+Na_2CO_3`C. `CH_2=CH-CH_3+H_2SO_4`D. None of these

Answer» Correct Answer - A
`C_2H_5Cl+2Na+Cl C_2H_5 to underset"butane"(C_2H_5-C_2H_5)+2NaCl`
This is called Wurtz reaction .
`C_2H_5COOH+Na_2CO_3 to underset"sodium propanoate"(2C_2H_5COONa)+CO_2+H_2O`
`CH_3-CH=CH_2+H^(+) HSO_4^(-)to underset"isopropyl hydrogen sulphate"(CH_3-undersetunderset(HSO_4)(|)(CH)-CH_3)`
