Talk:Organic Chemistry/Carboxylic acid derivatives

1).suggest a possible reaction mechanism for the synthesis of CH3CH2CH2CH2CO2H starting from CH3CH2CH2CO2H using Arndt-eistert method

2)show how you would prepare hexanoic acid starting from diethylmalonate [CH2(CO2Et)2] sodium ethoxid,and butyl bromide (use a reaction scheme).
