A high-boiling liquid, bp 202–204 ° C burns with a yellow, sooty flame. why? Pbl 4 does not exist because Pb-I bond initially formed during the reaction of Pb with I 2 does not release enough energy to unpair 6s 2 electrons and excite one of them to higher orbital to have 4 unpaired electrons around it. While PO2 and PbCl4 exist, PbBr2 and PbI4 do not. The Questions and Answers of PbI4 does not exist why ? Expert Answer 100% (2 ratings) Previous question Next question Get more help from Chegg. This problem has been solved! Related Questions. Question: While SnI4 Is Quite Stable, PbI4 Does Not Exist As A Stable Compound. COMEDK 2014: The non existence of PbI4 and PbBr4 is due to (A) highly oxidizing nature of Pb4+ ions (B) highly reducing nature of I- and Br- ions (C) Nov 26 2020 05:22 AM. Favorite Answer. There are, however PbI2 and PbI4. While SnI4 is quite stable, PbI4 does not exist as a stable compound. Relevance. If the answer is not available please wait for a while and a community member will probably answer this soon. 1 decade ago. Q.14 Suggest reasons why the B-F … Neither are good electrolytes. Pb 4+ being a strong acid (strong oxidant) will take up electrons from soft base (have fairly good reducing power) I- to oxidise … WCP. See the answer. Solution.pdf Next Previous. Why? Lead (II) iodide, which has PbI2 as its chemical formula, exists only this way and not in the form PbI4 as someone might guess. why? Why? +4 oxidation state is less stable and therefore gets reduced to +2.PbI 4 does not exist because the iodide ion reduces Pb(IV) to Pb(II) and itself gets oxidised to I 2 and therefore PbI 2 is formed. Dear User, Pb exist as Pb(IV) in PbI 4. Why is PbI4 not possible whereas PbCl4 exists? 4 Answers. Question from P-Block elements (Group-13 and Group-14),chemistry are solved by group of students and teacher of IIT JAM, which is also the largest student community of IIT JAM. So whenever a Pb compound is formed in +4 oxidation state then it would try to oxidise the counter anion and by this process it gets reduced to +2 oxidation state. Chlorine is a stronger oxidising agent and so can easily oxidise lead from +2 oxidation state to +4 oxidation state, therefore, PbCl4 exists whereas PbBr4 and Pbl4 do not exist because bromine and iodine are weaker oxidising agents and so cannot oxidise Pb2+ to Pb4+. PbI does not exist. While PO2 and PbCl4 exist, PbBr2 and PbI4 do not. Expert's Answer. Because of Inert Pair Effect Pb prefers to exist in 2+ oxidation state. Sodium fusion indicates that halogens, nitrogen, and sulfur are not present. Answer Save. P b C l 4 exists but P b B r 4 and P b I 4 do not because P b − I and P b − B r bonds initially formed during the reaction do not release enough energy to unpair 6 s 2 electrons and excite one of them to higher orbital to have four unpaired electrons around lead atom.
