The structural formulas for α-D-glucose and β -D-glucose has to be drawn. Concept introduction: Carbohydrates are defined as the polyhydroxy aldehyde or ketone or any compound that can be hydrolyzed to them. Glucose is an example of monosaccharide (Carbohydrates) and has a molecular formula C 6 H 12 O 6 . Glucose can exist in open structure as well as a ring structure. It is used as energy resource in most of the organisms.

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.

3. An unknown element, X, combines with chlorine to give a substance with the formula XC14. A chlorine analysis of the substance indicates that it contains 83.47% chlorine by mass. What element is X and what is the formula of this compound? (Hint: to identify an element or compound, identify its molar mass. Remember that Molar Mass = (grams A)/(moles A). Solve for each individually and then divide them to find molar mass.)

1. When hydrogen sulfide (H2S, MM = 34.08 g/mol) gas is bubbled into a solution of sodium hydroxide (NaOH, 40.00 g/mol), sodium sulfide (Na2S, 78.04 g/mol) and water (18.02 g/mol) are produced according to the balanced chemical equation shown below? H2S 2 NaOH --> Na2S 2 H₂O (a) Assuming the reaction goes to completion, how many grams of sodium sulfide are formed if 2.50g of hydrogen sulfide is bubbled into a solution containing 1.85g of NaOH? (20 pts) (b) Which reactant and how much of it remains after the reaction has been completed? (15 pts) (c) If only 0.400g of sodium sulfide was recovered, what is the percent yield of this reaction (5 pts)

The organic compound MTBE (methyltertiarybutylether) is used as a fuel additive that allows gasoline to burn more cleanly thus leading to a reduction in pollution. Recently, however, MTBE has been found in the drinking water of a number of communities. As a result several states are phasing out the use of MTBE as a fuel additive. A combustion experiment using 10.00 g of MTBE was found to produce 24.97g of CO2 and 12.26 g of H2O. (a) What is the empirical formula of MTBE assuming it contains C, H, and O only? (b) The molar mass of MTBE was experimentally determined to be 88.1 g/mol. Using this information what is the molecular formula of MTBE
