Question
A compound with the formula C,H,NOS reacts with excess hydrogen and a catalyst to yield a
compound with the formula C,H13NOS. The original compound could have:
two rings and two double bonds
more than one of these answers
O atriple bond and two double bonds
O two rings, a double bond, and a triple bond
one ring and three double bonds
Which of these is not a true statement?
O a) All Bronsted-Lowry bases are also Lewis bases.
O According to Bronsted-Lowry theory, water is both an acid and a bare.
O All Bronsted-Lowry acids are also Lewis acids
All Lewis acids contain hydrogen atoms
O All Lewis acids are in need of electrons (electron poor).

Contrary to expectations, the most stable conformation of 1,2-ethanediol is shown below.
H.
OH
OH
Knowing that it is the most stable conformation, the best reason for this stability must be:
In general, gauche conformations are lowest in energy
O tis stabilized by hydrogen-bonding
This is the anti- conformer
O This is a Newman Projection
It is higher in energy than the other conformations
Which of the following statements about the reaction below is correct?
ONa
E:OH
HOCH;CH3
pKa = 16
NAOCH;CH3 +
pKa = 20
O The reaction favors the products.
O None of these.
O The reaction actually makes a different product since it reacts with the solvent instead.
