According to Cahn-Ingold-Prelog sequence rules, the correct order of priority for the given groups is
- A \(-\mathrm{COOH}>-\mathrm{CH}_2 \mathrm{OH}>-\mathrm{OH}>-\mathrm{CHO}\)
- B \(-\mathrm{COOH}>-\mathrm{CHO}>-\mathrm{CH}_2 \mathrm{OH}>-\mathrm{OH}\)
- C \(\mathrm{Ni} / 140^{\circ} \mathrm{C}\) and \(\mathrm{Na} / \mathrm{NH}_3\) (liq. )
- D \(\mathrm{Pd} / \mathrm{BaSO}_4+\mathrm{H}_2\) and \(\mathrm{Na} / \mathrm{NH}_3\) (liq.)
Answer & Solution
Correct Answer
(D) \(\mathrm{Pd} / \mathrm{BaSO}_4+\mathrm{H}_2\) and \(\mathrm{Na} / \mathrm{NH}_3\) (liq.)
Step-by-step Solution
Detailed explanation
According to Cahn-Ingold-Prelog sequence rules, the priority of groups is decided by the atomic number of their atoms. When the atom (which is directly attached to the asymmetric carbon atom) of a group has higher atomic number, then the group gets higher priority. Groups with…
