Question

An organic compound a of molecular formula c2h6o on heating with excess of conc.h2so4 gives compound b of molecular formula c2h4 .compound b on reduction gives compound c of molecular formula c2h6. (a)name a, b and

c. (b) write the chemical equation for the conversion of a to

b. (c) what is the role of conc.h2so4 in above equation?

Answer 1

A -ethanol
B-ethene gas
C-ethane gas
Concept H2SO4 is dehydrating agent I.e. It removes water from ethanol

Answer 2

Here is your answer:

a) A: ethanol C2H6O

B: Ethene C2H4

C: ethane C2H6

b) C2H6O---(conc. H2SO4)----C2H4

c) here conc. H2SO4 is regarded as dehydrating agent which removes water from ethanol and changes into Ethene
