Answers for question 19 and 20
D
C
No, the reaction will not take place as written because the strongest acid reacts with the strongest base to give the weakest conjugate acid and the weakest conjugate base. D (pKa = 15.7) is a stronger acid than A
b
Phenol
Ethanol
In Phenol, the lone pair of electrons on oxygen delocalizes into the benzene ring (mesomeric effect) which reduces the electron density in the O-H bond. The O-H bonds is weaker and therefore breaks more easily in comparison to ethanol.
C3H6O.
b. Molecular mass= 58
c. 27.6 This is similar to the percent of Oxygen in the empirical formula.
