ISSUE:

Good morning, who can help me?
I need to know how Ozonolysis and Alkyne Hydration would be.
But when an alkyne has 1 or more triple bonds, which triple bond does water attack and why? and also with alkenes in ozonolysis. Which double bond does ozone attack and why? In the event that it had more than 1 double bond

Hello forumer.

Hello forum member, to complement Wilbert's answer, I see that your doubts are regarding Chemoselectivity (Reactivity of one functional group with respect to another in the same molecule), in the case of alkyne hydration it is NOT Chemoselective, there will definitely be a mixture of products .
In relation to Ozonolysis, YES and NO there will be Chemoselectivity, let me explain, when ozone is used in EXCESS, there is NO Chemoselectivity: but when there is a strict stoichiometric control of the amount of ozone, we do have chemoselectivity, which will depend on the stability of the double bond affected, here is the order and some examples.
