Question:medium
An organic liquid A containing C, H and O with p$K_a$ value 15.9, used in polishing woods, on heating with concentrated sulphuric acid gives a gaseous product B with the empirical formula CH$_2$. B decolourises bromine water as well as dilute permanganate solution. The compound A and B are respectively
