An ester (X) on hydrolysis gives an acid 'A' and alcohol 'B'. The sodium salt of 'A' on electrolysis gives ethane. When 'B' is distilled with aqueous bleaching powder it forms chloroform. Therefore 'X' may be
CH3 - COOC2H5
A' gives ethane on electrolysis so it is acetic acid 'B' gives chloroform so it is ethyl alcohol
