Question

Account for the following: i)Fluorine does no show variable oxidation states while other members of the halogen family exhibit variable oxidation states. ii)Iodine is more soluble in KIKI solution than in water. iii)Why do boiling points of noble gases increases down the group? iv)Why ammonia is a good complexing agent? v)Nitric oxide(NO) is a colourless gas becomes brown when released in air.

Answer 1

i)Fluorine has no d orbitals

ii) Iodine is more soluble in KI because iodine forms KI3 when it dissolved in KI.
kI + I2 →KI3

iii)The boiling points increase down the group because of the the size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.

Answer 2

Answer:

F has no d orbitals is the answer
