Which of the following yield both alkane and alkene

Answer»

KOLBE's reaction
Williamson's synthesis
Wurtz reaction
Sandmeyer reaction

Solution :Kolbe's method: Electrolysis of a CONCENTRATED aqueous solution of either sodium or potassium SALTS of carboxylic acids YIELDS alkanes/alkenes at anode
`CH_3COONa hArr CH_3COO^(-) + Na^(+)`n
Anode : `2CH_3COO^(-) overset(-2e^(-))to CH_3-CH_3+2CO_2`
Cathode :`2Na^(+)+2e^(-) to 2Na, 2Na+2H_2O to 2NAOH +H_2`
