The test for the presence of glucose with an aldehyde group is given to be found only in the open chain form but not in the cyclic form. This phenomenon is to be explained. Concept introduction: Carbohydrates are naturally occurring organic compounds. As the name implies carbohydrates are hydrates of carbon and have general formula of C X ( H 2 O ) Y . Basically, carbohydrates are polyhydroxy aldehyde and ketones , for examples, glucose and fructose. Glucose is a reducing sugar as it has an aldehyde group and its presence is detected by Tollen’s, Benedicts or Fehlings test. To determine: An explanation corresponding to the fact that the test for the presence of glucose with an aldehyde group is found only in the open chain form but not in the cyclic form.

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.

sketch the nature of the metal-alkylidene bonding interactions.

Part C The perspective formula of isoleucine, an amino acid, is provided below. HOOC H₂NIC H 川 CH3 CH,CH3 Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the C-2-C-3 bond. 1. Edit the Newman projection on the canvas. 2. Replace the appropriate hydrogens with the appropriate -CH3 or other groups. 3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar (bottom). Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move them by dragging or dropping them. That will break the projections structures. Only replace them! ▸ View Available Hint(s) 0 2 H± 3D EXP. L ד י CONT. 2 H 0 N о
