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.

**Task:**
**Draw the products of the reaction shown. Electron flow is indicated with curved arrows.**
![Reaction Mechanism]
- Reactant Structure:
- An organic molecule with a structure shown: **H₃C - CH₂ - Br**.
- The reaction involves an interaction with an oxygen anion (indicated with a negative charge and lone pairs of electrons).
- Curved arrows:
- One arrow is shown from the lone pair of the oxygen anion to the carbon atom bonded to the bromine (indicating nucleophilic attack).
- Another arrow shows the breaking of the C-Br bond, indicating departure of the bromide anion (Br⁻).
**Instructions:**
- Include all valence lone pairs in your answer.
- Include counter-ions, e.g., Na⁺, I⁻, in your submission, but draw them in their own separate sketcher.
- Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
- Separate multiple products using the + sign from the drop-down menu.
The reaction involves the following steps and observations:
1. Nucleophilic attack by oxygen anion on the carbon.
2. Departure of bromide anion as a leaving group.
**Detailed Explanation:**
The diagram shows a chemical reaction mechanism where electrons are moving from a nucleophile (a negatively charged oxygen anion) to attack an electrophile (the carbon bonded to bromine). Simultaneously, the bond between carbon and bromine is breaking, resulting in the formation of a carbon-oxygen bond and a bromide ion.
**Notes for Transcription:**
- Make sure to interpret and draw all valence lone pairs in your final answer.
- When including counter-ions, depict them separately in their own sketcher.
- Each product formed from the reaction should be drawn individually.
- Use distinct signs or symbols to separate multiple reaction products clearly.
This reaction exemplifies fundamental organic chemistry concepts such as nucleophilic substitution and electron flow, useful for educational purposes to understand reaction mechanisms.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdaac3699-bbcf-491f-ae47-6900b381c75d%2F375905e5-096a-40a5-b505-e09f84670d34%2Fqfe0b_processed.jpeg&w=3840&q=75)
