Question

For oxidizing alcohols, several oxidants – each with a multivalent central atom as the active species – can be used. When a secondary alcohol is oxidized to a ketone, how many bonds does the carbinol carbon have before and after the oxidation respectively?

• A. 2 – before, 1 – after
• B. 1 – before, 1 – after
• C. 1 – before, 2 – after
• D. 2 – before, 2 – after

Answer 1

The correct option is C

1 – before, 2 – after

The carbinol carbon is the one bearing the $OH$ group

$R-CH\left(OH\right)-R⟶RCOR$
