MCQ
Arrange these compounds in decreasing order of basic strength
- A$(i) > (ii) > (iii) > (iv)$
- B$(ii) > (iii) > (i) > (iv)$
- ✓$(iv) > (i) > (iii) > (ii)$
- D$(iv) > (i) > (ii) > (iii)$
✓
Answer
Correct option: C.
$(iv) > (i) > (iii) > (ii)$
c
Basic strength $ \propto \frac{{ + M}}{{ - M}} \propto \frac{{ + H}}{{ - H}} \propto \frac{{ + I}}{{ - I}}$
Basic strength $ \propto \frac{{ + M}}{{ - M}} \propto \frac{{ + H}}{{ - H}} \propto \frac{{ + I}}{{ - I}}$
