Why is the oxidation state of fluorine 1 in HOF?
Structure of HOF is: Since fluorine is more electronegative than oxygen, electrons from the bond between fluorine and oxygen are placed on fluorine atom when determining an oxidation number. Fluorine gets one extra electron so its oxidation number is -I (corresponding to charge -1).
What is the oxidation number of fluorine?
-1
Because the compound is neutral, the oxygen has an oxidation state of +2….Determining oxidation states.
| Element | Usual oxidation state | Exceptions |
|---|---|---|
| Group 2 metals | Always +2 | |
| Oxygen | Usually -2 | Peroxides and F2O (see below) |
| Hydrogen | Usually +1 | Metal hydrides (-1) (see below) |
| Fluorine | Always -1 |
What is the oxidation number of the F in F2?
EDIT: Fluorine in its gaseous form (F2) has zero oxidation state.
What is the oxidation number of oxygen in Hof of fluorine?
Oxidation number of oxygen in HOF is 0. Fluorine has +1 oxidation state. Let the oxidation state of F is +1. Oxidation state of OH is -1. Hence net charge on compound is zero. So, oxidation state of F is +1.
What is the oxidation number of Oh in Hof?
Fluorine, being the most electronegative element, has an oxidation state of -1. Remaining OH should have +1 state because the molecule on the whole is neutral. Moreover, the structure of HOF implies O having its 2 lone pairs intact. So it will have 0 (zero) formal charge.
Why is Flourine -1 but oh is -1?
Flourine will always be -1 because, well, it has no other oxidation states. In OH, O is -1+1=0 (O is more electronegative than H so it must be -1 in that respect, but +1 wrt to Flourine since flourine is more electronegative). H is +1, in order to “balance the neutraility” (Sum of oxidation states is 0 for an uncharged molecule).
What is hypofluorous acid (Hof)?
Hypofluorous acid (HOF) was first prepared in 1971 by fluorination of ice. HOF thus prepared is immediately removed from the reaction mixture otherwise it will be decomposed by HF,F2 or H2O. It is highly unstable and rapidly decomposes at room temperature with a half life of 9.30 minutes.
