1. Hydrogen peroxide acts both as an oxidizing and as a reducting agent in alkaline solution towards certain first row transition metal ions. Give examples

2. Give reason: Acid catalysed dehydration of t-butanol is faster than that of n-butanol.

3. Assertion - Reason type
Nuclide ³⁰Ai₁₃ is less stable than ⁴⁰Ca₂₀.
Nuclides having odd number of protons and neutrons are general unstable.

4. Assertion - Reason type
Al (OH)3 is amphoteric in nature
Al — O and O — H bonds can be broken with equal ease in Al(OH)3

5. Assertion - Reason type
