### Organic Reaction Mechanisms
**Question Set**
1. **Cyclopentane Reaction with Hydrobromic Acid (HBr)**
a) \( \text{Cyclopentene} \) + \( \text{HBr} \) \[R-O-O-R\] →
In this reaction, cyclopentene reacts with hydrobromic acid with the presence of a peroxide initiator (R-O-O-R). This condition usually implies a free radical addition reaction leading to anti-Markovnikov addition of HBr.
2. **Hydroboration-Oxidation Reaction**
b) \( \text{Cyclopentene} \) + \( \text{BH}_3, \text{THF} \) →
Cyclopentene reacts with borane (BH3) in THF (tetrahydrofuran) solvent. This is indicative of a hydroboration-oxidation reaction.
3. **Epoxidation Reaction**
c) \( \text{Cyclopentene} \) + \( \text{CH}_3\text{CH}_2\text{CH}_2\text{COOOH} \) →
Cyclopentene reacts with peroxypropionic acid (CH3CH2CH2COOOH) suggesting an epoxidation reaction.
4. **Halogenation Reaction**
d) \( \text{Cyclopentene} \) + \( \text{Br}_2 \) →
Cyclopentene undergoes a reaction with bromine (Br2), indicative of an electrophilic addition reaction resulting in a vicinal dibromide.
5. **Partial Hydrogenation Reaction**
e) \( \text{Alkyne compound} \) \[Lindlar's catalyst\] →
An alkyne compound reacts in the presence of Lindlar's catalyst which usually suggests a partial hydrogenation reaction leading to a cis-alkene.
6. **Sodium Metal Reaction with Alcohols**
f) \( \text{2 CH}_3\text{CH}_2\text{CH}_2\text{OH}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F02f056a6-4586-4fac-b275-0bb770c273e9%2F3af7eea1-8397-4be9-a9ec-40926b0b3215%2F3uau3j_processed.jpeg&w=3840&q=75)
