According to `CIP` sequence rule, the correct arrangement in order of decreasing priority isA. `OH gt COOH gt CH (OH)CH_(3) gtCH_(2)OH`B. `COOH gtOH gtCH_(2)OH gt CH(OH)CH_(3)`C. `OH gt CH_(2)OH gt COOH gtCH(OH)CH_(3)`D. `CH(OH)CH_(3) gtCOOH gtOH gtCH_(2)OH` |

Answer» Correct Answer - A `OH` has the highest priority because the directly attacjed oxygen atom has the highest atomic number. `-overset(O)overset(||)C-OH`equals`-overset(O)overset(|)underset((O))underset(|)C-OH`,i.e.`C(COO)`and takes priority over other ligands while `-overset(H)overset(|)underset(OH)underset(|)C-CH_(3)`,i.e.`C(OCH)` takes priority over `-overset(H)overset(|)underset(H)underset(|)C-OH`,i.e.`C(OHH)` |
