1.49.
a) All bond angles are approximately 109.5º, except for the C-O-H bond angle
which is expected to be less than 109.5º as a result of the repulsion of the lone
pairs on the oxygen.
b) All bond angles are approximately 120º.
c) All bond angles are approximately 120º.
d) All bond angles are 180º.
e) All bond angles are approximately 109.5º, except for the C-O-C bond angle
which is expected to be less than 109.5º as a result of the repulsion of the lone
pairs on the oxygen.
f) All bond angles are approximately 109.5º.
g) All bond angles are approximately 109.5º.
h) All bond angles are approximately 109.5º except for the C-C≡N bond angle
which is 180º.
