(a)
Interpretation: If the given characterisation can be applied to both cellulose and chitin, to cellulose only, to chitin only or to neither cellulose nor chitin has to be stated.
Concept introduction: Cellulose is the most abundant naturally occurring polysaccharide. The cell walls of plants are made up of cellulose. The second most abundant naturally occurring polysaccharide is chitin. It gives rigidity to most of the exoskeletons of crabs and lobsters.

- The number of hydrogens in an alkyne that has a main chain of 14carbons to which are attached a cyclobutyl ring, a benzene ring, an–OH group, and a Br is A. 34; B. 35; C. 36; D. 24; E. 43arrow_forwardHello! I have a 500 Hz H-NMR for 1,5-bis-(4-methoxyphenyl)-penta-1,4-dien-3-one. I need to label the signals with the corresponding H's. Then, find out if the two alkenes are cis or trans by calculating the J values. I believe that I have the H-NMR labeled correctly, but not sure if I got the J values correct to determine if the two alkenes in the compound will make the compound cis or trans.arrow_forwardWhat is the only possible H-Sb-H bond angle in SbH3?arrow_forward
