Chapter 1 Quiz |
1. (4 points) Rewrite the two compounds below to show all the bonds and
all the lone pairs.
Describe the hybridization and molecular geometry about
each carbon.
(Accurate pictures will be helpful but not required if your
description and hybridization are correct).
a) (CH3)2CHOH
all carbons are sp3 and tetrahedral
b) CH2=CHNH-
all carbons are sp2 and trigonal planar
2. (2 points) Write two good resonance forms for CH2N2 . The atoms are bonded CNN, with no rings.
3. (4 points) Complete acid-base reactions for
each of the following.
Predict whether each equilibrium will lie farther to the right or to the
left.
a) CH3OH + OH- <===> CH3O- + H2O
favored to the right (pKa 15.2 vs 15.7)
b) CH4 + NH2- <===> CH3- + NH3
favored to the left (pKa 60 vs 36)
