Compound A, C7H14, on hydroboration followed by oxidation yield compound B. When treated with chromic acid B is oxidized to a carboxylic acid C that can be resolved into enantiomers. Compound A on ozonolysis and work up yields the same compound D as is formed by oxidation of 3-hexanol with PCC. Identify compounds A, B, C and D and show your rationale.

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
