C) can give up electrons more readily than others.
Electrons because electrons are found in the electron cloud outside the nucleus.
As the pressure on the on a gas cofined above a liquid increases, the solubility of the gas will increase
this also happen when we lower the temperature
The bond order of BF₄⁻ is 1 and the bond order of BF₃ is 1.33
So, BF₃ is having more bond order than BF₄⁻.
In other words, BF₃ > BF₄⁻ ( You can write Bond Order or in B.O it's the abbreviation of Bond Order ).
