Ozone, Zn, H2O reaction

[rippinitez]

I understand that Ozone in combination w/ Zn and H2O will yield an aldehyde when reacted with an alkene.

But why does the alkyne react to yield a carboxyllic acid and aldehyde?

I thought the conditions were reducing. . .

Ozone is an oxidizing agent.

Never mind. I got it. In this situation alkynes react to make the carboxyllic acid. Alkenes to the aldehyde. My bad.
