An unknown alcohol with a molecular formula of C7H14O was oxidized to an aldehyde with HOCl. When an acidic solution of the alcohol was distilled,
two alkenes were obtained. The alkene formed in greater yield was determined to be 1-methylcyclohexene. The other alkene formed the original un-known alcohol when treated with BH3/THF followed by H2O2, HO-, and H2O. Identify the unknown alcohol.
Propose a structural formula for the product(s) when each of the following alkenes is treated with H2O/H2SO4. Why are two products formed in part (b), but only one in parts (a) and (c)?
(a) 1-Hexene gives one alcohol with a molecular for- mula of C6H14O.
(b) 2-Hexene gives two alcohols, each with a molecu- lar formula of C6H14O.
(c) 3-Hexene gives one alcohol with a molecular for- mula of C6H14O.
Show how the following compounds could be prepared from 2-methylpropane:
a. 2-bromo-2-methylpropane
b. 2-methyl-1-propene
c. 2-iodo-2-methylpropane
