C. d. e. H H H H The amine group is considered to be electron donating toward the ring by resonance, thus it will place a partial negative charge on the (relative) ortho and para positions. Draw three resonance structures for the product, showing the resulting charges at these positions. H 'H The carboxylic acid is considered to be electron withdrawing by resonance, thus it will place a partial positive charge on the (relative) ortho and para positions. Draw three resonance structures for the product, showing the resulting charges at these positions. H Based on the resonance structures, which of the aromatic protons is more shielded and which is less shielded? Which of these protons will appear at the larger chemical shift and which will appear at the lower chemical shift? Decide which of the protons should be labelled as He and Hc. Explain briefly.
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
