Chemistry, asked by MalavDoshi, 1 year ago

the valency of oxygen is 2 so how it can bond with 3 hydrogen to have a hydronium ion

Answers

Answered by atd01

H3O +
O has a valency (or formal charge) of -2 if you calculate it carefully

3 x (+1) + x = 1 (method to calculate formal charge)

3 + x = 1
x = -2

Hence no rule is violated

MalavDoshi: but it didn't answer my que I am asking with the valency of -2 how can it react with 3 atoms

MalavDoshi: or 3 protons

atd01: See, the more important thing is that the formal charge of O is not disturbed. It remains -2 which is a stable charge on an O atom

atd01: Don't get convinced that O can only bond with 2 atoms

atd01: Did you get my point?

atd01: In simpler words octet of Oxygen atom is complete if you carefully look at the structure of H3O+ ion

atd01: Just google it, if you don't know how it looks

Answer:

do you know about co - ordinate bond if no!.... then search it (enhance your knowledge yourself

Explanation: oxygen has 2 lone pairs in h20 molecule.....ahh rich and kind too

when h+ ion comes which has not even a single electron....BE KIND TO POORS

h20 is kind and thus donate its one lone pair(i.e 2 electrons(not its valence electron as they are engaged already) the bond formed due to lone pair is called co ordinate bond( search co ordinate bond for sister chemistry if u dont know about it)
