What is meant by a well-behaved function ? Illustrate with the help of a suitable diagram.

1) What is the selection rule for microwave absorption?
2) write the expression for rotational energy and name various term appearing in it?
3) If the value of rotational constant,B is 10cm^-1 for a diatomic molecule, what is the wave no. Of transition from j=3 to J=4 level?

For a molecule A, the plot of total polarisation Pm vs 1/T has zero slope while for molecule B, it has a finite positive slope. Out of CHCl3 and CCl4, which one could be molecule A and why ?

Draw a properly labelled (axes and signs) diagram of the molecular orbital obtained by the combination of s-orbital with py orbital along x axis. Is this orbital bonding, antibonding or non-bonding ?

Discuss the reducing and oxidising properties of h2o2

I'm wondering if you mix (50/50) 3%hydrogen peroxide at room temperature with 1% zinc acetate will the components react or will the combination remain as stable separate components simply diluted?

Can we change limiting reactant in chemical reaction to increase the amount of required product?
Like if zinc nitrate hexahydrate (15.0 g) reacts with sodium hydroxide (16.0 g) to produce zinc oxide (which was just 4.0 g), then can we change the amount of reactants in such a way so that the amount of zinc oxide produced is more?
