Interpretation:
An experiment for determining the maximum temperature around the year, along with a graph based on it, is to be represented.
Concept Introduction:
Graphs are used to depict the change in one quantity per unit to another quantity, taken from the set of data. These are easy to analyze and provide a clear picture of the scenario.
In graphs, one of the quantities is plotted on the y-axis and is termed as dependent variable. The other quantity is plotted on the x-axis and is called independent variable. The change in the dependent variable is dependent on the change in the independent variable.
A graph can be used to calculate the various trends which occur in that quantity over a certain period of observations. For example, decrease or increase, average decrease or increase and percentage increase or decrease etc.

Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book?
