Explanation

To solve the question, we need to analyze each statement one by one and determine whether they are true or false.

### Step-by-step Solution:

**(a)** **Peroxide ion as well as dioxygen molecule both are paramagnetic species.**

- **Analysis**:
- The peroxide ion (O₂²⁻) has 18 electrons (8 from each oxygen atom and 2 additional from the negative charge), which is an even number. Therefore, it is **diamagnetic**.
- The dioxygen molecule (O₂) has 16 electrons (8 from each oxygen atom), which is also an even number. However, O₂ has unpaired electrons in its π* antibonding orbitals, making it **paramagnetic**.

- **Conclusion**: Since the peroxide ion is diamagnetic and dioxygen is paramagnetic, the statement is **False**.

**(b)** **In the set of isomers, [Cr(H₂O)₆]Cl₃ and [CrCl(H₂O)₅]Cl₂·H₂O, both compounds can easily lose a water molecule on treatment with conc. H₂SO₄.**

- **Analysis**:
- The complex [Cr(H₂O)₆]Cl₃ has water molecules in the coordination sphere, and concentrated H₂SO₄ is a dehydrating agent that can remove water from coordination complexes.
- The complex [CrCl(H₂O)₅]Cl₂·H₂O also has water molecules in the coordination sphere and can similarly lose water upon treatment with concentrated H₂SO₄.

- **Conclusion**: Both complexes can lose water molecules, so the statement is **True**.

**(c)** **During transformation NO to NO⁺, bond length and magnetic behavior decreases.**

- **Analysis**:
- The bond order of NO is 2.5, which indicates a certain bond length and paramagnetic behavior due to unpaired electrons.
- In NO⁺, the bond order increases to 3, which results in a shorter bond length and a change from paramagnetic (NO) to diamagnetic (NO⁺) due to the removal of an electron.

- **Conclusion**: As bond order increases, bond length decreases and magnetic behavior changes from paramagnetic to diamagnetic. Therefore, the statement is **True**.

---

**(d)** **An ether is more volatile than alcohol both having the same molecular formula.**

- **Analysis**:
- Ethers have lower boiling points compared to alcohols because alcohols can form hydrogen bonds due to the presence of -OH groups, while ethers cannot.
- Therefore, for compounds with the same molecular formula, the ether will be more volatile than the alcohol.

- **Conclusion**: The statement is **True**.

### Final Answer:
- (a) False
- (b) True
- (c) True
- (d) True

### Code: FTTT
