Question

Fluorine shows only -1 oxidation state whereas other halogens show along with -1 also +1, +3, +5 and +7. Explain.

Answer 1

Answer:

other halogens has has valency of 1 and they react with all other metals and non metals

Answer 2

Explanation:

Fluorine shows only -1 oxidation state whereas other halogens show along with -1 also +1, +3, +5 and +7,Due to following reasons.

(1)Since the size of fluorine is very small in comparison to the other halogen.

(2)The electronic configuration of the fluorine is $1s^{2} 2s^{2} 2p^{5}$So,it does not contain any d-orbital,due to which its shown only -1 oxidation state.
