Document Description
1. What is the number of atoms per unit cell in a body centered cubic structure ?
2. Define osmotic pressure.
3. For the reaction 1 the rate law is expressed as rate What is the overall order ‘of this reaction ?
4. Write the IUPAC name of the compound:
5. Why do nitro compounds have high boiling points in comparison with other compounds of same
molecular mass ?
6. State ‘Pauli’s exclusion principle’. Explain giving an example how this principle limits the maximum
occupancy of an energy level in an atom.
OR
State ‘Aufbau principle’ and give the order in which the energies of orbitals increase and hence they are
filled in that order. 2
