Base strength of (1) CH ₃ CH ₂ (2) H ₂ C = C H and (3) H - C C is in the order of
Options
- A(2) > (1) > (3)
- B(3) >(2)>(1)
- C(1)>(3)>(2)
- D(1) > (2) > (3)
Correct answer
D. (1) > (2) > (3)
Step-by-step solution
Key Idea : Stronger the acid, weaker is its conjugate base. The strength of their conjugate acids are in the order : HC CH > H ₂ C = CH ₂> CH ₃- CH ₃ Therefore, the correct order of strength of their conjugate base is : CH ₃ CH ₂^ > H ₂ C = C H > HC C
