Question

Comparison of Basic strength of NH3,
NF3and (CH₃)3N
​

Answer 1

Answer:

NH3  is more basic than NF3.

In NF3,N is less electronegative than F, hence bond pair shifts more towards F, thereby δ positive charge density on N increases, hence tendency to donate electron decreases. In NH3,N is more electronegative than H, hence bond pair shifts towards N in N−H, thereby negative charge density on N increases, hence tendency to donate electrons increases. Hence NH3 is more basic as compared to NF3.
