The mechanism for the acid catalyzed cyclisation of D-fructose to β-D-fructofuranose should be drawn. Concept introduction: Hemiacetal are formed for the compound having both hydroxyl group and aldehyde group in acidic condition. The –OH group of compound attacks the carbonyl group of the same compound, thereby a ring is formed by the carbon atoms and oxygen atom of –OH group with incorporating into the ring. Acid catalyzed reaction are followed by the deprotonation of Hydronium ion to water molecule and then protonation of this water molecule will return to Hydronium ion will take place.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Can u help me figure out the reaction mechanisms for these, idk where to even start

Hi, I need your help with the drawing, please. I have attached the question along with my lab instructions. Please use the reaction from the lab only, as we are not allowed to use outside sources. Thank you!
