Answer to Question 1

1,4-Cyclohexadiene has a greater heat of hydrogenation. This is because 1,3-cyclohexadiene is stabilized by conjugation of the two pi bonds.

Answer to Question 2

1,3-Cyclohexadiene, in which the two pi-bonds are conjugated, absorbs at a higher wavelength than 1,4-cyclohexadiene.
