**Reagents and Conditions:**
1) DIBAL
2) H₂O
**Description:**
This reaction involves the use of Diisobutylaluminum hydride (DIBAL) followed by hydrolysis. DIBAL is a selective reducing agent that can reduce esters to aldehydes under controlled conditions.
----
#### Reaction 8
**Starting Material:**

**Reagents and Conditions:**
CrO₃, H₂SO₄/H₂O
**Description:**
This reaction utilizes chromium trioxide (CrO₃) in a mixture of sulfuric acid and water, known as Jones' reagent, to oxidize the primary alcohol to a carboxylic acid.
----
#### Reaction 9
**Starting Material:**

**Reagents and Conditions:**
1) Ph₃P
2) n-butyllithium
**Products:**
- Product 1: Alkene
- Product 2: Aldehyde
**Description:**
This reaction sequence involves the Wittig reaction, where triphenylphosphine (Ph₃P) and n-butyllithium are used to form an ylide from the bromoalkane, leading to the formation of an alkene and subsequently an aldehyde.
----
#### Reaction 10
**Starting Material:**

**Reagents and Conditions:**
1) CH₃CH₂MgBr
2) H₂O
**Description:**
This reaction involves the use of a Grignard reagent (CH₃CH₂MgBr) which adds to the carbonyl group forming an alcohol upon aqueous workup.
