Expert Academic Help for Courses
Organic chemistry is one of the most dreaded fields of study for new chemistry students with good reason. It exposes the students to extremely challenging concepts and volumes of information. It also tests many students in their critical thinking skills in a manner never seen before.
Organic chemistry, by description, is deceptively simple. You can call it the chemistry of life as it is based on a single element, carbon. This does not begin to describe the vast network of different compounds that can be formed. Once you begin study in this field, you will notice very quickly that carbon was given its own field justifiably.
Organic chemistry is the principle means by which we arrive at the molecules we use for pharmacological purposes. Without synthesis, we would need to rely on the discovery of molecules in nature, hoping that plants and animals make a unique elixir to cure our ails. With the vast repertoire of organic synthesis techniques at our disposal, the sky is the limit in terms of what can be made.

Molecular Weight by Freezing Point Depression
For unknown sample #1, there is 2 g of the unknown sample and 10 mL of water. The freezing point was -1.7 C so Td=1.7. In unknown sample #2, there is 2g of the sample and 10 mL of water. Freezing point = -1.8. So Td = 1.8. How do I obtain the molecular weights for these two unknown samples?
Electronic theory: explaining observations and devising suitable reaction sequences
1. On the basis of electronic theory, explain the following observations: a. The -N(CH3)2 group is an ortho, para director, and strongly activates the ring, whereas the -N(CH3)3 group is a meta director and deactivates the ring toward electrophilic substitution. b. The -NO2 group is a meta director, and its presence on the ...continues
