CHXI11:THE P-BLOCK ELEMENTS

316606 Fluorine does not show positive oxidation states because

1 It is most electronegative element

2 It forms only anions in ionic compounds

3 It cannot form multiple bonds

4 It shows non-bonded electron pair repulsion due to small size

CHXI11:THE P-BLOCK ELEMENTS

316607 Which of the following halogens does not exhibit a positive oxidation number in their compounds?

1

I

2

Br

3

Cl

4

F

Explanation:

$F$ is the most electronegative atom. So, it cannot exhibit positive oxidation state.
