Answer:
B) exothermic.
Explanation:
Hello!
In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.
In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:
B) exothermic

5 monochloro derivative will be yield to when 2 methylbutane react with chlorine. 4 carbon atom are present in 2 methylbutane which react with chlorine. The chiral carbon that is carbon anti bonding react with chlorine to form four different groups around it hence it will stereoisomer
If earth didn't rotate the global winds would stay on the same speed of rate because the wind isn't moving without rotation in the earths axis.
To arrange these elements according to the atomic radius (smallest to largest) would be:
