1. Determine the center of mass coordinates for formaldyde, H2C=0. Start with a planar structure with C as the origin. The HCH angle is 120 degrees. The C-0 bond length 1.2 A, the C-H bond length is 1.0 A.
2. Calculate the rotational constants: A, B and C in MHz. Use A (MHz) = 505379 MHz amu A2/ la (amu A2).
3. Determine three transitions from the energy level handout and compare to the JPL database. Determine the percent error of the three transitions.
4. The NIST bond length webpage gives the average C-H length as 1.068 A and a minimum C=0 bond length as 1.11 A. How does that affect the highest frequency transition from problem 3?
Draw (a) planar conformation and (b) nonplanar (chair) conformation of trans 1,4-dimethylcyclohexane.
Calculate the theoretical yield of C2H5Cl when 124 g of C2H6 reacts with 219 g of Cl2 , assuming that C2H6 and Cl2 react only to form C2H6Cl and HCl.
How many grams each of the following, per 1000g of water in your car radiation, are needed to give equal protection against freezing down to -10 degrees C? (a) Methyl alcohol, CH3OH (b.p. 65 deg C), (b) ethyl alcohol,

Peonin is a red pigment found in the petals of peony flowers. Why do you think peonin is bonded to two hexoses? What monosaccharide(s) would be produced by acid-catalyzed hydrolysis of peonin?
To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.59 mg/mL was mixed with 1.00 mL of the plant stream material, and analysis of the mixture gave a peak area of 463 for peak A and 425 for peak B. What is the concent..
