Problem 31SP

Draw complete Lewis structures, including lone pairs, for the following compounds.

Step-by-Step Solution:
Step 1 of 3

Answer :

Lewis dot structure and lone pairs of compounds :

a)pyridine :

 Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. The pyridine ring occurs in many important compounds, including azines and the vitamins niacin and pyridoxine.

Nitrogen has one lone pair of electron .

b)Pyrrolidine :

Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH2)4NH. It is a cyclic secondary amine, also classified as a saturated heterocycle. It is a colourless liquid that is miscible with water and most organic solvents. It has an ammonia-like, but characteristic odor. In addition to pyrrolidine itself, many substituted pyrrolidines are known.

Nitrogen has one lone pair of electrons .

c) Furan :

 Furan is simply a five-membered aromatic compound with the molecular formula C4H4O . ... Furan's five-membered ring is actually comprised of four carbon atoms and one oxygen atom. The oxygen is bonded to the ring via two single bonds.

In addition to this, each carbon atom has one hydrogen atom attached. Furan's Lewis structure looks like this

Because the lone pairs of electrons are allylic, i.e. they are located next to the double bonds, furan can exhibit resonance

http://chemistry.stackexchange.com/questions/573/the-most-stable-furan-resonance-structuresAs you an see, one of oxygen's lone pairs of electrons is actually delocalized in the ring, which is why furan is considered an aromatic compound (I won't go into too much detail about why that is). This implies that the actual structure of furan can best be described using a hybrid model that looks like this

d)gamma amino butyric acid :

Gamma-aminobutyric acid (GABA), converted from the principal excitatory neurotransmitter glutamate in the brain, plays a role in regulating neuronal excitability by binding to its receptors, GABA-A and GABA-B, and thereby causing ion channel opening, hyperpolarization and eventually inhibition of neurotransmission.
