Answer 1

(E) $TBr_{5}^{2-}$

Answer 2

Step 1:

Identify the oxidation states of each element

From the table, we have the following oxidation states for each element:

- Q: +3
- R: +1, +2, +3
- S: +2, +3, +4, +5
- T: +3, +4, +5, +6, +7

Step 2:

Determine the possible compounds based on oxidation states

We need to check if the given compounds can exist based on the oxidation states of the elements involved.

(A) $QCl_{2}$:

- For $QCl_{2}$ to be valid, Q would need an oxidation state of +2. However, Q only has an oxidation state of +3. Therefore, $QCl_{2}$ is not a valid compound.

(B) $RO_{3}^{2-}$:

- For $RO_{3}^{2-}$ to be valid, R would need an oxidation state of +6 (since oxygen typically has an oxidation state of -2). However, R only has oxidation states of +1, +2, and +3. Therefore, $RO_{3}^{2-}$ is not a valid compound.

(C) $SH_{2}$:

- For $SH_{2}$ to be valid, S would need an oxidation state of -2 (since hydrogen typically has an oxidation state of +1). However, S does not have a negative oxidation state; it only has positive oxidation states (+2, +3, +4, +5). Therefore, $SH_{2}$ is not a valid compound.

(D) $T(NO_{3})_{2}$:

- For $T(NO_{3})_{2}$ to be valid, T would need an oxidation state of +2 (since nitrate, $NO_{3}^{-}$, has a charge of -1). However, T does not have an oxidation state of +2; it has oxidation states of +3, +4, +5, +6, +7. Therefore, $T(NO_{3})_{2}$ is not a valid compound.

(E) $TBr_{5}^{2-}$:

- For $TBr_{5}^{2-}$ to be valid, T would need an oxidation state of +5 (since bromine typically has an oxidation state of -1). T has an oxidation state of +5, which makes $TBr_{5}^{2-}$ a valid compound.
