Help I have an exam tomorrow!?

Um, well there's a double bond there... they usually react with other things in an addition reaction or a cleavage reaction.

Under mild acid conditions would mean there is more likelihood for a double bond, an area of high electron density, to react with something that might like some more electrons yes? In an addition reaction?

Then there is going to be an carbocation (electron-deficient carbon) on one side of where the double bond used to be. What is left that might be attracted to the positive carbon? The oxygen on the water.

The oxygen has too many bonds for its liking now, and wants to get rid of one of the hydrogens - which another oxygen on a water molecule will happily associate with to make another H3O+ (acid) molecule.

So the overall reaction is the addition of H and OH across the double bond; if you draw and follow this reaction on paper you will know whether it's Markovnikov or anti-Markovnikov (i.e. which carbon will get the OH and which one will get the H).

Good luck on your test.

It is addition reaction of alkene. The product will be alcohol (2-propanol)

CH3--CH=CH2 + H2O-----> CH3--CH(OH)--CH3

In this reaction we have added water molecule on Carbon carbon double bond Hydrogen (H) of water molecule will add on CH2 group of double bond while Hydroxyl part (OH) of water molecule will add on CH.

Remember hydrogen will always attach to the carbon which already contains large no of hydrogen atoms which In this case is CH2 group. This rule is called Markovnikov's rule.and there is a reason for this. But i think this explanation is enough for you. By the way best of luck for your exams

I can't help with that i'm afraid, but you should probably get some sleep! Good luck xx
