1. 120; 139: In pyridimine, the bond angles between the atoms are approximately
degrees and the C-C bond lengths of pm are intermediate between normal
C-to-C sigma and pi bonds.
2. Sp2: In pyridimine, The atoms of the ring are each hybridized, and each
contributes a single electron to the conjugated p system for a total of six p electrons,
making the ring aromatic just like benzene. ns in an ____
ng (like the
3. Sp2: The nitrogen atom of pyridine contains a lone pair of electro
hybrid orbital that is oriented in the same plane of the atoms in the ri
hydrogens that project from each carbon atom)
4. The Atomic Orbital Picture of the p-Electron Network in Pyridi ne.: What is
being shown?
5. substitution: pyridine is aromatic and tends to undergo reactions rather
than addition (which would destroy the aromaticity).
6. First is the ability of pyridine to accept hydrogen bonding interactions
from water molecules due to the lone pair of electrons on the nitrogen atom.
In addition, the electronegative nitrogen creates a relatively strong dipole
moment in the pyridine molecule, thus making pyridine a polar compound
overall. There is a shift of electrons away from the carbons and towards the
nitrogen, making the ring carbons partially positive and the nitrogen partially
negative.: There are several factors that explain the ability of pyridine to dissolve in
water. What are they?

**Dipole-dipole attractive forces between the pyridine molecules raise the
boiling point as compared to benzene.: In addition to the solubility differences
brought about due to polarity, the boiling point of pyridine is also higher
than that of benzene, even though the molecular weight difference between the two
compounds is negligible.
8. With KNO3 / HNO3 / H2SO4 at 300 degrees: pyridine can be nitrated under what
conditions?
9. pyridinium ion: Name this
10. Br2 / H2SO4 at 400 degrees: pyridine can be bromated under what conditions?
