Welcome to Chem Zipper.com......: What are the explanation of Different Bond length and Bond Angle In P4O6 and P4O10 :

(1) According to Bent Rule Loan Pair prefer to Stay to in those atomic orbital have more (S) character.

(2) In case of P₄O₆ molecules atomic orbital containing loan pair have more (S) character and less (P) character hence shorter bond length while remaining orbitals have less (S) character and more (P) character hence longer bond length (X₁) than (X₂) in P₄O_{10 .}

(3) We know that On increasing % s character in hybrid orbital, the bond length decreases while bond angle increases.

(3) In Case of P₄O₆ (O-P-O) bond is Smaller due to higher P character in atomic orbital than orbital containing (O-P-O) in P₄O₁₀. (have more S character )
