MCQ
Which of the following is correct
  • A
    Basicity of phosphorous acid is $3$
  • B
    Perchloric acid has one peroxy linkage
  • C
    Solid $SO_3$ does not have cyclic structure
  • ✓
    Borazine has zero dipole moment
✓

Answer

Correct option: D.
Borazine has zero dipole moment
d
Basicity of phosphorous acid $= 2 (H_3PO_3)$

Perchloric acid has no peroxy linkage $(HClO_4)$

Solid $SO_3$ have cyclic structure.

$B_3N_3H_6$ $\left( {\mu  = 0} \right)$ Borazine
