- Four
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Tertiary amines have structure: \[ R_3N \]
Step 1: Distribute 4 carbons among 3 groups. Possible combination: \[ 1 + 1 + 2 \]
Step 2: Structure. \[ (\text{CH}_3)_2\text{N} - \text{C}_2\text{H}_5 \] Only one arrangement possible. Conclusion: \[ \text{Number of tertiary amines = 1} \]
