Question

The functional groups —OH, —COOH, —CHO, —OCH3 attached to a chiral carbon is in the preference order

Solution

Correct option is

OCH3 > OH > COOH > CHO

If two atoms directly attached to the double bond have the same atomic number, then the elative priority of the groups is determined by a similar comparison of the atomic numbers of the next elements in the groups. Thus, the preference order of given group is

            OCH3 > OH > COOH > CHO
