Problem 1: Draw the following three Newman projections for the carbon-carbon bond in Br-CH2-CH2-Br (Hint: bromine atom will act much the same as the methyl group in butane, see your notes)
a. Anti conformation
b. Eclipsed (Give only one of the possible options)
c. Gauche (Give only one of the possible options)
Problem 2: Name the following compounds:
Problem 3: Using skeletal structure, draw any four constitutional isomers that have the formula C7H16
A 1.00-g solid sample containing a mixture of NaCl and H3C6H5O7, a triprotic acid, is dissolved in 15 ml of water. Titration of the acid solution requires 25.40 mL of 0.1598 M NaOH solution to reach the endpoint.
What is the final pH after 1 drop (0.05 mL) of 6M HCl is added to 1.0 L of freshly prepared pure water that was originally at a pH of 7.0. Is there a significant pH change

calculate the volume of carbon dioxide, measured at 273 k and 1.01 x 10 5 Pa, which would be produced when 1.25 g of calcium carbonate reacts completely with the hydrochloric acid.
a 12.6 g sample of NH4NO3 is dropped into a constant-pressure calorimeter containing 175 g of water at 23.5 C. What temperature will the water reach, assuming that the calorimeter container does not gain or lose any heat?
Methyl chloride, methylene chloride, chloroform, and carbon tetrachloride are all part of what group that has had one, two, three, or four hydrogen atoms replaced respectively with chlorine atoms?
