Question

A compound xon heating with excess conc. Sulphuric acid at 443 k gives an unsaturated compound y.Xalso reacts with sodium metal to evolve a colour less gas z. Identify x,y,z. Write equation of chemical reaction of formation of y.Also write the role of sulphuric acid in the reaction

Answer 1

compund x is ethanol(C2H5OH) when ethanol is treated with concentrated sulphuric acid than an unsaturated compound of Ethanol called ethene formed so, compound y is ethene(CH2=CH2).

when ethanol reacts with sodium then the colourless gas hydrogen is formed so the colorless Z is hydrogen(H) .
