Question

fluorine exists only +1 oxide state whereas other halogens exists +1,+3,+5and+7 oxide state.plz explain​

Answer 1

Answer:

The electronic configuration of fluorine is 1s2 2s2 2px2 2py2 2pz1 Fluorine is one electron deficient to attain noble gas configuration. If it gains one electron it attains stability & it is more electronegative element.by gaining 1 electron it is showing -1 oxidation state. In fluorine due to the absence of d-orbital it can’t excite electrons. Hence it can’t show +1, +3 oxidation state. In other elements like chlorine; bromine vacant d-orbitals are available so that they can excite the electron and shows higher oxidation states.
