Compound A exist in equilibrium with its tautomeric form, compound B. An IR spectrum of a mixture of A and B exhibits four signals in the region 1600-1850 cm^-1. These signals appear at 1620, 1660, 1720 nd 1740 cm^-1. a. Identify the source for each of these four signals and provide a justification for the location of the signal at 1660 cm^-1
b. For most simple ketones, the concentration of the enol tautomer is almost negligible at equilibrium. However, in this case, the concentration of B is significant. Provide a justification for this observation.
c. The IR spectrum of compound C lacks a signal at 1720 cm^-1. Draw the tautomer of C and then determine which tautomeric form predominates at equilibrium. Explain your choice.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
