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.
![### Reaction Identification Exercise
**Problem Statement:**
Identify the major and minor product(s) that are expected for the following reaction. Select all that apply.
**Given Reaction:**
- **Reactants:** A cyclohexane derivative with an OTs (tosylate group) at one position and a CH₃ (methyl group) at another position.
- **Reagent:** DBU (1,8-Diazabicyclo[5.4.0]undec-7-ene), a strong non-nucleophilic base.
**Instructions:**
Choose the major product expected from the reaction.
**Response Section:**
- An incorrect choice was made, as indicated by the message: "Your answer is incorrect."
**Product Options:**
- Four possible structures, presented as molecular diagrams, are available.
- A checkbox is located next to each structure for selection.
- One of the structures was selected.
**Feedback:**
- Users need to identify the correct major product based on their understanding of the reaction mechanism, which might involve elimination pathways common to such conditions (e.g., E2 mechanism with DBU).
### Explanation:
- **Tosylate (OTs)** groups are good leaving groups, often involved in elimination reactions.
- **DBU** is a strong base, which promotes elimination (usually E2) rather than substitution.
- The task involves determining products based on these chemical principles.
