Question Paper
Out of a and which one has higher ionisation energy? Justify your answer.
Write the nuclear reaction responsible for the energy in the Sun.
Radius of a cation is 82 pm while that of an anion B-is 164 pm. On this basis, predict the coordination number of cation in AB crystal.
2. Answer any two parts:
State Hund's rule and give justification for it.
Predict, whether the following molecules. are microwave active or inactive:
CCl4, HCl, CH3Cl and N2
Calculate the frequency of the radiation required to eject the photoelectrons at a velocity of 5 x 10^6 from sodium metal. The threshold frequency of sodium is 4·6 x 10^14 Hz.
Write the molecular orbital configuration of N2 and calculate its bond order. Is it paramagnetic or not?
Calculate the wave numbers of first and second spectral lines in the Lyman series of hydrogen atom.
Predict the shape of PCl5 based on VSEPR theory. Explain the type of hybridisation in it.
What is binding energy What are the effects of fJ -decay, fJ+-decay and electron capture on the atomic number Z and the mass number of the parent atom?
Calculate the force constant for a diatomic molecule if it absorbs radiation at 1·463 x 10^6 and its reduced mass is 1·425 x 10^-26 kg.
A molecule A2B has 3 modes of vibration. Is it a linear or a non-linear molecule?
Draw a labelled diagram depicting variation of radial probability density against for an electron in 2s orbital.
For a molecule the plot of total polarisation Pm vs 1/T has zero slope while for molecule it has a finite positive slope. Out of CHCl3 and CCl4, which· one could be molecule A and why?
What is dielectric. constant The capacitance of a capacitor in vacuum. is 8·9 x 10^-12 F. When the capacitor is filled with a dielectric, the capacitance is 80·1 x 10^-12 F. Calculate the dielectric constant of the dielectric material.
