(a)
Interpretation:
The given diagram should be predicted as exothermic or endothermic or no clear conclusion and explanation has to be given if it has no clear conclusion.
Concept Introduction:
The study of heat that is related with chemical reaction is called as Thermochemistry and their reactions are called as thermo-
The process in which energy is required to break bonds is called as endothermic process. In other words, endothermic process takes place upon the breakage of bonds.
The process in which energy is released upon the formation of new bonds is called as exothermic process. In other words, exothermic process takes place upon the formation of bonds.
The type of reaction is determined by the formation or breakage of bonds.

Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right.

Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure.
