Write the equations for the following lab. preparations:
(a) Ethane from sodium propionate,
(b) Ethene from Iodoethane,
(c) Ethyne from calcium carbide,
(d) Methanol from Iodomethane.
(a) Ethane from sodium propionate
C2H5COONa+NaOHCaO−−−→300oCNa2CO3+C2H6
(b) Ethene from iodoethane
C2H5I+KOH(alcoholic)⟶C2H4+KI+H2O
(c) Ethyne from calcium carbide
CaC2+2H2O⟶Ca(OH)2+C2H2
(d) Methanol from iodoethane
CH3l+NaOH⟶CH3OH+Nal
