Thank You for the mechanism, but I still having problems with figuring it out. For example I know that for the condensation of ethanal is going to produce
CH3CH=CHCOH, but when it comes to larger sequences I begin to have troubles.
Here's how carry out the problem.
CH3COCH2CH2CH2CHO ----> CH3CH(OH)CH2CH2CH2CHO-----> ?
then i get lost. I guess my question is where would place the additional hexan-5-onal after I deprotanate the hexan-5-onal.
Thank You
