Question

a compound A wih molecular formula c2h4 is obtained by heating compound B with conc h2so4 b is a powerful fuel identify a and b and write the chemical equation involved

Answer 1

c2h5oh=c2h4+h20
at 160-170°c in presence of conc. h2so4
b=ethanol
a=ethene

Answer 2

Compound A = ethene(c2h4)

Com.B=ethanol(ch3ch2oh)

On heating ethanol with con.h2so4

It becomes ethene

Ch3ch2oh------------ c2h4

(h2so4)
