Draw a mechanism for this reaction

For example, in the reaction between ethene and hydrogen bromide, one of the two bonds between the two carbon atoms breaks. That bond is simply a pair of electrons. Those electrons move to form a new bond with the hydrogen from the HBr. At the same time the pair of electrons in the hydrogen-bromine bond moves down on to the bromine atom..

In the lithium aluminium hydride reduction water is usually added in a second step. The lithium, sodium, boron and aluminium end up as soluble inorganic salts at the end of either reaction. Note! LiAlH 4 and NaBH 4 are both capable of reducing aldehydes and ketones to the corresponding alcohol. The mechanism for this reaction, first we protonated the OH to form water as a good leaving group so water left and that gave us a carbocation with a plus one formal charge on this carbon, this benzylic carbon. So we have a benzylic carbocation in our mechanism. Let me just go ahead and draw that in here.
