Write the reaction equations: Ethan – Ethen -Thethylene -Uxus Aldehyde

Make an equation:
1. H3C – CH3 = H2 + H2C = CH2 – dehydrogenation reaction, ethylene (ethen) is released;
2. H2C = CH2 + H2O = H3C – CH2 – it – hydration, ethanol is obtained;
3. H3C – CH2 – it + Cuo = CH3 – CHO + CU + H2O – Ethanol oxidation with copper oxide when heated, acetic aldehyde is highlighted.
The above equations show the connection of alkanes, alkenes and aldehydes. Reaction products have practical applications, for example, acetic aldehyde is necessary for the synthesis of acetic acid.
