The formula for calculating the amount
of money in a savings account that begins with an initial principal
value (P) and earns annual interest (i) for (n) years is: P(1 +
i)n
Note that i is a decimal, not a percent interest rate: .1 NOT
10%

Compound A and compound B both have molecular formula
C6H12. Both compound produce epoxides when
treated with MCPBA. The epoxide resulting from compound A was
treated with aqueous acid (H3O+) and the
resulting diol has no chirality centers. Propose two possible
structures for compound A. The epoxide resulting from compound B
was treated with (H3O+) and the resulting
diol was a meso compound. Draw the structure of compound B.
Compound A with the molecular formula (C3H8O) on oxidation gives
