A solution of 0.4 g/mL of a pure R enantiomer in a 1.0 dm (i.e., 10 cm) polarimeter rotates plane polarized light by +8.8°. What is the rotation observed on this solution in a 3 dm polarimeter?

The observed rotation of a solution of 1.2 g of a compound in 10 mL of water is +0.75 degrees. If the pathlength is 10 cm, what is the specific rotation of the compound?

a. Rank A-C in order of increasing wavelength absorption. b. Compound C has an absorption that shifts bathochromically when examined inincreasingly polar solvents. What does this tell you about the magnitude and sign of theexcited-state dipole moment relative to the ground-state dipole moment. Explain yourreasoning. c. What is a hyperchromic effect

A student completed a similar lab experiment and got an εavg of 56 M-1cm-1. If their change in absorbance (∆A) for the first 1.5 minutes was 1.089 and the cuvette was 1.0 cm wide, what was the rate for the first 1.5 minutes?    Give your answer to the nearest 0.001 M/min.

7 Consider the following compound and decide if it is chiral or achiral. Show your work by determining whether each molecule has a plane of symmetry or inversion symmetry а) Br b)

Can I get help with number 2

What is the structure based on the HNMR?

The specific rotation of (R)-2-butanol is 13.5° counterclockwise. A sample containing (R)-2-butanol was made by dissolving 1.75 g into a solution with a total volume of 3.55 mL. The light source was a sodium D line and the temperature was 25° C. The length of the sample tube was 12.5 cm. What was the observed rotation of the sample? "Use three significant figures for your answer and the correct sign.

How can IR spectroscopy be used to distinguish between each pair of isomers?
