Bond angle is 107⁰ in

detailed solution

Correct option is B

All oxo acids of Chlorine are monobasic….contain one O-H group/molecule ;All the pi bonds in these acids or their oxanions are dπ-pπ bonds ;In all oxo acids of Chlorine the hybridization of Chlorine atom is sp3 ;Cl-O bond  order….ClO- 1ClO2->ClO3->ClO4- ;Bond angle….ClO--no bond angle …. diatomic species; ClO3-- 1070 (3 bp+ 1 lp ); ClO4-- 109.50(4 bp); In ClO2- - 1110( 2 bp + 2 lp )….bp-bp repulsions dominate lp-lp repulsions ;Acidic strength, oxidizing power, bleaching power…..HClO>HClO2>HClO3>HClO3 ;Basic strength…….ClO->ClO2->ClO3->ClO4- ;ClO- does not exhibit resonance ; ClO4- cannot undergo disproportionation…'Cl' is in its highest O.S ;Stability….HClO
