1hmm.. just searched a little and found that..halogens do not usually show even oxidation states...and such compounds are often thermally unstable
nw this may be the reason
1but there is one more thin that supports the fact that Cl should hav lesser one...
that Cl has more electrons, and it is going to cause more inter electronic repulsions, and so it should be easier to remove electron from Cl
1only thing is i see that Chlorine does not want half filled.... so doesn't go to +2......n Sulphur also hates half filled ..........
but HALF FILLED means MORE STABILITY
maybe this doesn't apply to 3p.....
maybe it involves the fact that some transitions in electron r more favored than others.....
1if that's the reason i thnk the reason which i mentioned has a strong priority to wat rickde has mentioned......................
1well i'd like to say something.....
chlorine always has -1, +1, +3,....
no +2.........it looks like chlorine for some reason does not want to be in +2 ......[12]
1kaunse book main hai ye...........
is any explanation given ??
I do thnk sulpur ka hi jyada hoga
since after removal of one electron frm outer most shell of sulpur , it attains half filled p-orbital stability state but not Chlorine
after removal of one elctron frm outer shell configurations r
Sulpur - 3p3
chlorine - 3p4
so if u wanna remove another electron then chlorine will easily do that to attain stability of half filled orbital but sulpur will do that with difficulty as sulpur is already in a stable state....
1dude subho.its pearson's not a useless book.we cn be sure of data given there n NET confirms it too[1]
1i fund that the second ionization energy values for Sulpur is 2252 KJ/mol while that of Chlorine is 2298 KJ/mol strange ??[7]
49@cute_cat: i think u have checked for first ionisation..i think![1][1]
39Agree with manmay...sulfur attains stability due to half filled shell in +1 oxidation state. Chlorine attains that in +2. It should be that way, ideally.
But..ionisation enthalpy would also depend on some other factors isn't it?
Go across a period, ionisation enthalpy increases due to the addition of an electron in the same shell(effective nuclear charge increases). So S has less IE than Cl.
1even the sources on the internet say the same....sulfur has a little less
S-2251kJ/mol
Cl-2297.3kJ/mol
1it is given in pearson publication[1]well i also thought exctly same!but dunno y book says so?
