Question

1. which of the following
properties does not correspond
to the order HI< HBr< HCl< HF
O ionic character
O thermal stability
O dipole moment
O reducing power​

Answer 1

Step-by-step explanation:

The correct order of the reducing power is HF<HCl<HBr<HI. On moving from HF to HI, the stability of hydrogen halides decreases. Due to this, reducing power increases on moving down the group.

HF is not a reducing agent and HI is the strongest reducing agent. The trend in the reducing power of hydrogen halides can also be explained on the bases of the increasing size of the halide ions from fluoride to iodide
