(a)
Interpretation: The maximum number of stereoisomers that could exist for 1,2-cyclohexanediol needs to be determined, if the formula is 2n ( n = number of stereocenters).
Concept Introduction: Organic compounds are the compounds which are mainly composed C and H atoms. The branch of chemistry that deals with preparation, reactions, and properties of organic compounds. The compounds with same molecular formula and different structural formula are called as isomers. Isomers can be classified as constitutional isomers and stereoisomers.
Constitutional isomers can be defined as the pair of molecules with the same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula but they have different arrangement of atoms in the three-dimensional space.
Optical isomers are type of stereoisomers which have same molecular and structural formula but they have different arrangement of atoms in the three-dimensional space. The essential condition for a molecule to be optical isomer is the presence of chiral carbon atom.

Interpretation: The reason of three stereoisomers of 1, 2-cyclohexanediol rather than calculated value 4 needs to be explained.

- * How many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4? * If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of NaOH and in the final volume (2.000 L) and assume random error.arrow_forwardYou are tasked with creating a calibration curve for the absorbance of cobalt solutions of various concentrations. You must prepare 5 standards with concentrations between 1.00 mg/L and 10.0 mg/L Co2+. You have a stock solution with a concentration of 40 mg/L Co2+ and all the standard lab glassware including transfer pipets and flasks. Explain how you would make your 5 standard solutions of various concentrations, including what glassware you would use to measure and prepare each solution.arrow_forwardPredict the product and write the mechanism.

Specifically, where does it come in during rubber or textile production and what is the chemical processes?arrow_forwardA researcher has developed a new analytical method to determine the percent by mass iron in solids. To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard with the new method returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Does the new method produce a result that is significantly different from the standard value at the 95% confidence level?arrow_forwardCreate a drawing of an aceral with at least 2 isopropoxy groups, and a total of 11 carbon atomsarrow_forward

NBS, peroxide, Aarrow_forwardIn addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…arrow_forwardBriefly describe a eutectic system.arrow_forward
