the NaOH is there to deprotonate the ketone to produce a nucleophile that can attack via substitution reaction. Does that make sense?

Do you know the general pKa for an aldehyve vs ketone? That might help you with these.

Not too much. I'm just frustrated becuase I'm super close but I don't know what to change.

All I know is that NaOH is a catalyst in this reaction. I dont know anything.

If you mix the benzyladehyde with NaOH, you won't really get a reaction....the product would be too unstable. Thus, NaOH reacts with the cyclopentanone (deprotonating the cyclopentanone) to make it more reactive toward benzaldehyde.

Guys I'll look back at that in a sec. Can you help me with this one? http://gyazo.com/a58a420c9eb11373d6f6a0731736cf91.png

The last one is gringard reaction. Very important reaction in organic chemistry.

What do I change it to?

Note that the oxygen on the ketone carries a partial negative charge \(\delta^-\), while the carbon has a partial positive charge \(\delta^+\). Similarly, the magnesiumbromoethane, the MgBr carries a \(\delta^+\), the carbon \(\delta^-\). Etc. Basically, + goes with - and so forth.

Then, water protinates the organometalic structure. Organometallics are pretty unstable and highly reactive. So, you get an alcohol. |dw:1377973073150:dw|

The CrO\(_3\) promotes a jones oxidation reaction. I am not really sure what it does, because it tends to form alcohols \(\rightarrow\) ketones. But I find it hard to form one since it is already a 3ยบ alcohol. Maybe a very unstable product forms.
