Which of the following is the correct order for increasing bond angle ?
  • A
    $NH_3 < PH_3 < AsH_3 < SbH_3$
  • B
    $H_2O < OF_2 < Cl_2O$
  • C
    $H_3Te^+ < H_3Se^+ < H_3S^+ < H_3O^+$
  • D
    $BF_3 < BCl_3 < BBr_3 < BI_3$
✓

Answer

$(c)$ Correct order of bond angle:
$(a)\, NH_3 < PH_3 < AsH_3 < SbH_3$ (As $E.N.$ value of $C.A.$ $\uparrow$  bond angle $\downarrow $) 

$(b)\, OF_2 < OH_2 < OCl_2$

$(c)\, H_3Te^+ < H_3Se^+ < H_3S^+ < H_3O^+$
$(d)\, BF_3 = BCl_3 = BBr_3 = BI_3$
