Reactions of Alkyl and Aryl halides
In organic chemistry, an alkyl halide is formed when an atom of hydrogen is switched by a halogen in a hydrocarbon or aliphatic compound. An aryl halide is formed when an atom of hydrogen is substituted by a halogen atom in an aromatic compound. Metals react with aryl halides and alkyl halides and they also go through nucleophilic substitution reactions and elimination reactions.
Zaitsev's Rule in Organic Chemistry
Alexander Zaitsev (also pronounced as Saytzeff), in 1875, prepared a rule to help predict the result of elimination reactions which stated, "The favored product in dehydrohalogenation reactions is that alkene that has the majority of alkyl groups attached to the double-bonded carbon atoms."
Tosylate
Tosylates are important functional groups in organic chemistry, mainly because of two important properties which they possess:
Alkyl Halides
A functional group is a collection of several atoms or bonds with certain characteristic chemical properties and reactions associated with it. There is a presence of a halogen atom (F, Cl, Br, or I; it represents any halogen atom), as a functional group in alkyl halides. Therefore, it can be said that alkanes that contain a halogen compound are called alkyl halides.
![**Title: Stereochemical Transformation Exercise**
**Instructions:**
**Show the correct stereochemistry when needed!**
Fill up the boxes with the required reagents to effect the following transformation.
**Diagram Explanation:**
- The diagram consists of a series of boxes connected by arrows, outlining the steps needed for a chemical transformation.
- The transformation begins with an alkyne group indicated by a triple bond (≡) on the left.
- The target molecule is a benzyl alcohol represented at the top-right, featuring a benzene ring attached to an OH group with a side chain.
- There are several boxes along the pathway where reagents or conditions must be added:
- The first box on the left awaits reagents for the initial transformation step.
- The next box to its right, connected by a downward arrow, awaits the next set of reagents.
- Following horizontal arrows, there are subsequent boxes for further reagents leading to the final product shown at the top-right.
- Each arrow between boxes signifies a separate reaction step in the synthesis.
**Objective:**
Identify and fill in the appropriate reagents in each step box to achieve the target transformation, ensuring correct stereochemistry throughout the process.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd7bf774f-fe51-4121-93c6-6dec45c8cd41%2Fc3735449-ebf1-4bfc-902d-522ccd64b154%2Fbm7y2iq_processed.jpeg&w=3840&q=75)
