Account for the following: (i) PbX_(2) is more stable than PbX_(4) (X = Cl, Br) (ii) PbCl_(4) is more stable than SnCl_(4) but PbCl_(2) is more stable than SnCl_(2), (iii) PbCl_(4) is less stablethan SnCl_(4) ?

Account for the following: (i) PbX_(2) is more stable than PbX_(4) (X

1.	Account for the following: (i) PbX_(2) is more stable than PbX_(4) (X = Cl, Br) (ii) PbCl_(4) is more stable than SnCl_(4) but PbCl_(2) is more stable than SnCl_(2), (iii) PbCl_(4) is less stablethan SnCl_(4) ?
Answer» <html><body><p></p>Solution :(i) <a href="https://interviewquestions.tuteehub.com/tag/due-433472" style="font-weight:bold;" target="_blank" title="Click to know more about DUE">DUE</a> to inert pair effect, the +2 <a href="https://interviewquestions.tuteehub.com/tag/oxidationstate-2906371" style="font-weight:bold;" target="_blank" title="Click to know more about OXIDATIONSTATE">OXIDATIONSTATE</a> of Pb is more stablethan `+4`. Hence, `PbX_(2)` is more stable than `PbX_(4)`. (ii) <a href="https://interviewquestions.tuteehub.com/tag/stability-651358" style="font-weight:bold;" target="_blank" title="Click to know more about STABILITY">STABILITY</a> of `+4` oxidationstate decreases down the groupwhile that of `+2`oxidationstate increases due to inert pair effect. (iii) Same as (ii).</body></html>
