Correct order of bond angle in given species is : — p Block Elements Chemistry Question

💡 Solution & Explanation

SiO4^4- (sp3, 109°28'). $\angle$Cl-N-Cl in NCl3 > $\angle$Cl-P-Cl in PCl3 because participation of s-orbital in hybridization decreases from NCl3 to PCl3. $\angle$Cl-P-Cl in PCl3 > $\angle$H-Sb-H in SbH3 (almost pure p-orbitals). $\angle$H-Sb-H > $\angle$H-Te-H (due to two lone pairs on Te).
