Question

Which gas librated a compoundxonheatingwithexcess conc sulpheric acid at 443 k gives an unsaturated y ,x also react with sodiummetal to evolve a colourlessgas z identifyx y z and write chemical balanced equation?

Answer 1

whenethanol react with sulphuric acid at 443k it gives ethene

C2H5OH (H2SO4 at 443k)--> CH2=CH2

C2H5OH + Na --> C2H5ONa+ H2

So,

x --》 Ethanol (C2H5OH)

y --》 Ethene ( CH2CH2)

z --》 Hydrogen (H2)
