Question

In which process do you expect the entropy to be the most favorable?

a. Addition of h2 to 1-butene

b. Substitution of fluoride for bromide in methyl bromide

c. elimination of hydrogen fluoride from ethyl fluoride to produce ethene

d. protonation of hydroxyl group in ethanol

Is the answer C? Explain why please.

In which solvent would a substitution reaction between methyl iodide and sodium cyanide take place at the fatest rate?

a. acetic acid

b. ethanol

c. water

d. dimethylsulfoxide

please explain

Explanation / Answer

1. The answer should be A, hydrogenation of butene. the partially negative side (the double bond) attracts an electrophile very fast.

2. Fastest rate would be the reaction with acetic acid.
