The enthalpy of vaporization of ethanol is 38.56 kJ/mol. It has a boiling point of 351.44 K. What is the difference in entropy between ethanol's liquid and gaseous states at 351.44 K. What I'm asking is what is the size of the "jump" on the Sm ver..
Why E2 is favored over SN2, Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
