Answer:
C. 3.40 ppm, singlet
Explanation:
Given the information from the question .we have to select the best representation for represents the predicted approximate chemical shift and coupling for hydrogen(s). In this case, there is no neighboring hydrogen .Thus there won’t be any split .the best option answer is C. 3.40 ppm, singlet . Therefore the correct answer or option is C. 3.40 ppm, singlet.
The correct answer that would best complete the given statement above is option B. Heat in a substance is an example of a kinetic energy. Kinetic energy is a kind of energy that is in motion. We can feel the kinetic energy of heat through their temperatures because heat is being transferred.

Change in temperature affects the rate of reaction since it causes a change in the number of collisions per unit time. These collisions cause the breaking of bonds and formation of new ones giving out new products. An increase in temperature increases the rate of collisions hence increasing the rate of reaction while a decrease in temperature leads to a decrease in the rate of reaction due to the decreased number of collisions per unit time. thus the correct choice for blank A is: B. the number of collisions between molecules and for blank B: decrease.
