What is the correct IUPAC name of the compound ?

easy MCQ 1 mark Class 12 · Chemistry · Amines
  1. 1-Propylamine
  2. Propylamine
  3. Propan-1-amine
  4. Propanamine
Answer
Propan-1-amine

The correct answer is Propan-1-amine — Thus the correct IUPAC name is propan-1-amine.

Step-by-step solution

  1. Identify the longest carbon chain containing the –NH group; it has three carbon atoms, so the parent alkane is propane.
  2. Number the chain so that the –NH group gets the lowest possible locant; this gives position 1.
  3. Replace the –ane suffix of the parent with –amine and add the locant in front of the name.
  4. Thus the correct IUPAC name is propan-1-amine.
Common mistake: Using the alkane name without the ‘‑1‑’ position
