Concept explainers
Interpretation:
The location of bonding electrons in polar covalent bond and those in a non-polar covalent bond needs to be explained.
Concept introduction:
Covalent

Answer to Problem 115A
In polar covalent bond, location of electrons is near more electronegative atom but electrons shared equally in non polar covalent bond.
Explanation of Solution
Polar molecules have uneven electron density and they have dipole with partially charged ends. Due to unequal sharing of electrons in polar molecule, electrons spent most of the time near more electronegative atom. But in case of non-polar molecule electrons are shared equally.
Polar molecules consist of permanent dipoles due to positive and negative charge ends.

Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³.
