Account for the following observation: (i) AlCl_(3) is Lewis acid (ii) Though fluorine is more electronegative than chlorine yet BF_(3) is a weaker Lewis acid than BCl_(3) (iii) PbO_(2) is a stronger oxidising agent thatn SnO_(2) (iv) The +1 oxidation state of thallium is more stable than its +3state.

Answer» <html><body><p></p>Solution :(i) `AlCl_(3)` is a Lewis acid because the central Al <a href="https://interviewquestions.tuteehub.com/tag/atom-887280" style="font-weight:bold;" target="_blank" title="Click to know more about ATOM">ATOM</a> has a sextel of electrons after <a href="https://interviewquestions.tuteehub.com/tag/sharing-25803" style="font-weight:bold;" target="_blank" title="Click to know more about SHARING">SHARING</a>. It is electron deficient and `AlCl_(3)` <a href="https://interviewquestions.tuteehub.com/tag/behaves-894569" style="font-weight:bold;" target="_blank" title="Click to know more about BEHAVES">BEHAVES</a> as a Lewis acid. <br/> (ii) For answer, consult <a href="https://interviewquestions.tuteehub.com/tag/section-25668" style="font-weight:bold;" target="_blank" title="Click to know more about SECTION">SECTION</a> 11.12. <br/> (iii) +2 oxidation state of Pb in `PbO_(2)` is more stable than +2 oxidatin state of Sn in `SnO_(2)` due to greater <a href="https://interviewquestions.tuteehub.com/tag/inert-1043160" style="font-weight:bold;" target="_blank" title="Click to know more about INERT">INERT</a> pair effect. This means that `PbO_(2)` is a stronger oxidising agent than `SnO_(2)` and changes to +2oxidisionstate more easily. <br/> (iv) For answer, consult section 11.2.</body></html>
