Reactive Intermediates
In chemistry, reactive intermediates are termed as short-lived, highly reactive atoms with high energy. They rapidly transform into stable particles during a chemical reaction. In specific cases, by means of matrix isolation and at low-temperature reactive intermediates can be isolated.
Hydride Shift
A hydride shift is a rearrangement of a hydrogen atom in a carbocation that occurs to make the molecule more stable. In organic chemistry, rearrangement of the carbocation is very easily seen. This rearrangement can be because of the movement of a carbocation to attain stability in the compound. Such structural reorganization movement is called a shift within molecules. After the shifting of carbocation over the different carbon then they form structural isomers of the previous existing molecule.
Vinylic Carbocation
A carbocation where the positive charge is on the alkene carbon is known as the vinyl carbocation or vinyl cation. The empirical formula for vinyl cation is C2H3+. In the vinyl carbocation, the positive charge is on the carbon atom with the double bond therefore it is sp hybridized. It is known to be a part of various reactions, for example, electrophilic addition of alkynes and solvolysis as well. It plays the role of a reactive intermediate in these reactions.
Cycloheptatrienyl Cation
It is an aromatic carbocation having a general formula, [C7 H7]+. It is also known as the aromatic tropylium ion. Its name is derived from the molecule tropine, which is a seven membered carbon atom ring. Cycloheptatriene or tropylidene was first synthesized from tropine.
Stability of Vinyl Carbocation
Carbocations are positively charged carbon atoms. It is also known as a carbonium ion.
Draw intermediate or product
![**Educational Content for Drawing a Structural Formula**
**Instructions:**
In the reaction provided, you are required to draw a structural formula for the intermediate compound.
**Chemical Reaction:**
\[ \text{CH}_2=\text{CHCH}_2\text{CH}_2\text{CH}_3 + \text{Br}_2 \rightarrow \text{CH}_2\text{Cl}_2 \]
**Guidelines:**
- **Stereochemistry:** You do not need to consider stereochemistry for this task.
- **Hydrogen Atoms:** It is not necessary to explicitly draw hydrogen atoms.
- **Counter-ions:** Do not include counter-ions such as \(\text{Na}^+\) or \(\text{I}^-\) in your answer.
**Tools Available:**
Below the text, there are drawing tools for creating the structural formula. These include options for adding carbon rings, bonds, and various atoms.
This task is designed to enhance understanding of hydrocarbon reactions and the formation of intermediates. Make sure to consider the addition of bromine to the alkene double bond in your drawing.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe00d5964-792b-4512-b566-b098925a990b%2Fe414dcc9-19ad-4983-9ba5-2d9f178ecf70%2Fyrjltt.jpeg&w=3840&q=75)
![**Organic Chemistry Reaction Problem**
**Objective:**
Draw a structural formula for the major organic product of the following reaction.
**Reaction Details:**
- Reactants:
- Alkene:
\[
\text{CH}_2 = \text{C} \text{(CH}_3) \text{(CH}_2\text{CH}_2\text{CH}_2\text{CH}_3\text{)}
\]
- Bromine:
\[
\text{Br}_2
\]
- Solvent:
\[
\text{CH}_2\text{Cl}_2
\]
**Instructions:**
- Show product stereochemistry **only if** the reactant alkene has both carbons of the double bond within a ring.
- Do not show stereochemistry in other cases.
- If enantiomers are formed, just draw one.
**Diagrammatic Tools:**
- Draw and edit tools including bond types, shapes, and text annotations are available for constructing chemical structures.
