MCQ
$H_2O_2$ in basic medium reduces $I_2$ to form
- A$I^-$
- B$IO_3^-$
- ✓$I_3^-$
- D$IO_4^-$
✓
Answer
Correct option: C.
$I_3^-$
c
Due to larger size of iodine atom it can accommodate upto seven small fluorine atoms around, it while due to smaller sizes of chlorine and bromine atoms do not accommodate seven fluorine atoms, i.e., steric factor dominate in case of chlorine and bromine.
