Answer:
A chemical reaction that involves the release of energy in the form of heat or light is called <em><u>Exothermic</u></em><em><u> </u></em><em><u>Reaction</u></em><em><u>.</u></em>
Answer:-
The reaction of 2-bromopropane reacts with sodium iodide in acetone is an example of Sn2 reaction.
The I - attacks from backside to give the transition state for both.
If we compare the transition state for cyclobromopropane 2-bromopropane then we see in case of cyclobromopropane transition state, one of the H is very close to the incoming I -.
This results in steric strain and less stability of the transition state. Hence 2-bromopropane reacts with sodium iodide in acetone over 104 times faster than bromocyclopropane.
Protons because each element has a different number. Example, Oxygen has 8, Nitrogen has 7, Carbon has 6, etc.
