(I) – OH (II) – C ≡ C – (III) – OR (IV) – NH₂

(IV) > (I) > (II) > (III)

(IV) > (I) > (III) > (II)

(I) > (IV) > (III) > (II)

(II) > (III) > (IV) > (II)

Priopirity order of functional groups of organic chemistry →

The decreasing order of priority of functional gro p is →

R → OH

R – NH₂
∴ so the the order is (I)) > (IV) > (III) > (II)

1. R – OR

2. R – NH₂.
3. R – O – R

4. R – C ≡ C – R

∴ Option ' C ' is correct.
