Basics in Organic Reactions Mechanisms
In organic chemistry, the mechanism of an organic reaction is defined as a complete step-by-step explanation of how a reaction of organic compounds happens. A completely detailed mechanism would relate the first structure of the reactants with the last structure of the products and would represent changes in structure and energy all through the reaction step.
Heterolytic Bond Breaking
Heterolytic bond breaking is also known as heterolysis or heterolytic fission or ionic fission. It is defined as breaking of a covalent bond between two different atoms in which one atom gains both of the shared pair of electrons. The atom that gains both electrons is more electronegative than the other atom in covalent bond. The energy needed for heterolytic fission is called as heterolytic bond dissociation energy.
Polar Aprotic Solvent
Solvents that are chemically polar in nature and are not capable of hydrogen bonding (implying that a hydrogen atom directly linked with an electronegative atom is not found) are referred to as polar aprotic solvents. Some commonly used polar aprotic solvents are acetone, DMF, acetonitrile, DMSO, etc.
Oxygen Nucleophiles
Oxygen being an electron rich species with a lone pair electron, can act as a good nucleophile. Typically, oxygen nucleophiles can be found in these compounds- water, hydroxides and alcohols.
Carbon Nucleophiles
We are aware that carbon belongs to group IV and hence does not possess any lone pair of electrons. Implying that neutral carbon is not a nucleophile then how is carbon going to be nucleophilic? The answer to this is that when a carbon atom is attached to a metal (can be seen in the case of organometallic compounds), the metal atom develops a partial positive charge and carbon develops a partial negative charge, hence making carbon nucleophilic.

![### Reaction Analysis and Stoichiometry
Given the reaction below, answer the following questions:
\[ \text{CH}_4(g) + \text{S}(g) \rightarrow \text{CS}_2(g) + \text{H}_2\text{S}(g) \]
#### Questions:
**A.** Balance the equation above.
**B.** Is the sulfur oxidized or reduced in the reaction? **Show charges.**
**C.** Given \( 3.841 \times 10^{25} \) molecules of \( \text{CH}_4 \), how many moles is this?
**D.** Given 21.3 grams of Sulfur gas, how many moles of \( \text{H}_2\text{S}(g) \) could be formed?
#### Solutions:
**A.** To balance the equation, one must make sure that the number of each type of atom on the left side of the equation is equal to the number on the right side.
\[ \text{CH}_4(g) + 4\text{S}(g) \rightarrow \text{CS}_2(g) + 2\text{H}_2\text{S}(g) \]
**B.** Determine whether sulfur is oxidized or reduced:
In \(\text{S}_8\) (solid sulfur), the oxidation state of sulfur is 0. In \(\text{CS}_2\) and \(\text{H}_2\text{S}\), the oxidation states of sulfur are as follows:
- In \(\text{CS}_2\): Sulfur has an oxidation state of -2.
- In \(\text{H}_2\text{S}\): Each sulfur atom has an oxidation state of -2.
Since sulfur goes from an oxidation state of 0 to an oxidation state of -2, it is **reduced**.
**C.** To convert molecules of \( \text{CH}_4 \) to moles:
Use Avogadro’s number \( (6.022 \times 10^{23}) \):
\[ \text{Number of moles} = \frac{\text{Number of molecules}}{\text{Avogadro's number}} \]
\[ = \frac{3.841 \times 10^{25}}{6.022 \times 10^{23}} \approx 63](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8e803b3c-73d2-4762-ae70-129489ba72a5%2Fa3692db9-03f3-437e-b8be-89a838dce9dd%2Fid4x42m_processed.jpeg&w=3840&q=75)
