(a) All form monobasic oxyacids
(b) All are oxidizing agents
(c) Chlorine has the highest electron-gain enthalpy
(d) All but fluorine shows positive oxidation states
Show Answer
Solution:
- (d) Due to high electronegativity and small size, $F$ forms only one oxoacid, HOF known as fluoric (I) acid.
Flourine has -1 oxidation state in most of its compound. Oxidation number of $F$ is +1 in HOF.
