Acid catalyzed hydration of alkenes is the reaction in which a pi bond is broken and an alcohol added to the Markovnikov position when carried out in water. When alcohol is used as the reaction solvent an ether will form following the same reaction mechanism.
The video below is Part 5 in my Alkene Reaction Mechanism series and will take you through the acid catalyzed alkene hydration reaction in step by step detail

Ma’am you are an amazing teacher and I love the way you help in grasping the concepts in a short and crispy manner.
Ma’am i also had a query.Did you upload videos or general method of preparation of alkenes/alkynes as well?
If you have could you tag the url because i am unable to find them.
Great videos! was very helpful…keep it up!
Hi Leah. Awesome stuff. Could you explain why this reaction is faster than just distilled water on its own? It seems the e+/nu- logic would equally follow. Is it because of the strength of the h2o vs h3o bonds?
so I came acorss this alkyne and the reaction is added hgso4, h2so4/h20. would you treat it the same. as th above example
Alkynes react differently. Your product will be a ketone or aldehyde
Alkynes will form carbonyls through keto-enol tautomerization
Francis B. Banks (Ph. D., MRSC) says
Hi. Great videos, but I notice a slight mistake. A pH of 0.1 means the [H+] is 0.1 mol per litre, or 1 mole of H+ in 10 L of water. 10 L of water contains about 555 mol, so that means 1 H+ for every 555 H2O molecules.
What about Sylvolysis? Isn’t it Hydration with an additional step?
I don’t understand your question Aana. Solvolysis is when the solvent reacts. In acid catalyzed hydration the acid is a catalyst and water is the solvent and nucleophile
