The message
from "michael adams" contains these words:

Commercial growers use acetylene gas which is also given off
by ripening fruit, bananas especially.

Not enough hydrogen.

Eyhylene (heavy carburetted Hydrogen - C2H2) is used for ripening
tomatoes - by some producers. Acetylene is used for welding - (CH2)


acetylene = ethyne = C2H2

Acetylene/ethyne is C2H - (sorry, typo up above)

ethylene = ethene = C2H4

According to Chambers, Ethylene/ethene/heavy_carburetted_hydrogen is
C2H2 - but Collins agrees with you that it's C2H4. C2H4 sounds much more
likely. And all my organic chemistry books are in boxes in some barn or
other somewhere in Norfolk...
