I need help with the step 5 and 6 please

 

Draw the major organic product. Do not draw non-bonding electrons.
K2Cr207
H2SO4
HOʻ
distill
What occurs in step 1 of the mechanism?
The hydroxy group of the alcohol attacks the chromium to form a pentavalent chromium.
The hydroxy group of the alcohol is protonated.
O The hydroxy group of the alcohol is deprotonated.
What occurs in step 2 of the mechanism?
O The protonated alcohol intermediate is deprotonated.
O A hydroxy group on chromium is deprotonated.
A proton a to the protonated oxygen is deprotonated.
Steps 3 and 4 involve a series of proton transfer steps. In step 3, a hydroxy group on the chromium is protonated to form a good
leaving group. In step 4, a hydroxy proton is deprotonated, a new t bond is formed and the leaving group is removed to give the
chromate ester.
