In the following question a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below.
Assertion (A): A molecule of $$\mathrm{SF}_4$$ is see-saw shaped, while that of $$\mathrm{CIF}_3$$ is T-shaped.
Reason(R): SF$$_4$$ has two lone pair of electrons. But CIF$$_3$$ has one pair of electrons.
On the basis of VSEPR theory, match the molecules listed in Column I with their shapes given in Column II.
| No. | Column I | No. | Column II |
|---|---|---|---|
| A | $$\mathrm{ClF_3}$$ | P | Sea saw |
| B | $$\mathrm{BrF_5}$$ | Q | Pentagonal bipyramidal |
| C | $$\mathrm{SF_4}$$ | R | Square pyramidal |
| D | $$\mathrm{IF_7}$$ | S | T-shaped |
Identify the pair of molecules, both of which have positive values of Dipole moment.
Given below are 4 molecular species/ions. Identify the species/ion which exhibits diamagnetic nature.
$$[\mathrm{A}]=\mathrm{N}_2^{+} \quad[\mathrm{B}]=\mathrm{O}_2^{-} \quad[\mathrm{C}]=\mathrm{B}_2 \quad[\mathrm{D}]=\mathrm{C}_2$$
