Draw the major product(s) of the following reactions including stereochemistry when it is appropriate. CH;CH2-C=C-CH3 1 Cl2 • Consider E/Z stereochemistry of alkenes. If there is more than one major product possible, draw all of them. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
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 Problem:**
Draw the major product(s) of the following reactions including stereochemistry when it is appropriate.
\[ \text{C}_3\text{H}_3\text{CH}_2 - \text{C} \equiv \text{C} - \text{CH}_3 \quad + \quad \text{1 Cl}_2 \quad \rightarrow \]
**Instructions:**
- Consider E/Z stereochemistry of alkenes.
- If there is more than one major product possible, draw all of them.
- Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
---
**Explanation:**
This reaction involves the addition of chlorine (\( \text{Cl}_2 \)) to an alkyne (\(\text{CH}_3\text{CH}_2 - \text{C} \equiv \text{C} - \text{CH}_3\)). The instructions emphasize considering the stereochemistry of the resultant alkene if applicable, and to present all potential major products derived from the reaction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcec0a2e7-2b0b-4046-8671-803627d53536%2Ffe37edb1-ef93-43d3-bbe3-faa425946090%2Fbw4usjj_processed.jpeg&w=3840&q=75)
