Organomagnesium compounds
The interaction of alkyl halide with Mg metal in a suitable ether solvent is the common method for the synthesis of the Grignard reagent.
Hydrolysis Grignard Reactions and Reduction
Organomagnesium halides are Grignard reagents. Francois Auguste Victor Grignard, a French chemist who received the Nobel Prize in Chemistry in 1912, created these highly useful reagents.

**Topic: Synthesis of Substituted Alkynes**
**Question:**
9.6 What terminal alkyne and alkyl halide react to give the following compound?
**Reaction Overview:**
- **Reactant:** A sodium amide (NaNH₂) reagent is used to facilitate the reaction.
- **Product:** The target compound depicted is a branched alkyne featuring a triple bond connected to an ethyl group and an isopropyl group.
**Note:**
The hint suggests observing the nature of the alkyne substituents—in this case, indicating that one alkyne substituent is primary and the other is secondary.
### Diagram Explanation:
The diagram consists of:
1. **Chemical Arrow:**
- Indicates the direction of the reaction from left to right, with NaNH₂ above the arrow.
2. **Structural Formula of Product:**
- Features a carbon chain with a triple bond (alkyne).
- On one side, an ethyl group is attached.
- On the other, an isopropyl group is connected.
**Hint Explanation:**
The hint emphasizes the structural nature of the substituents around the alkyne:
- **Primary Substituent:** Contains a carbon attached to only one other carbon.
- **Secondary Substituent:** Contains a carbon attached to two other carbons.
This information is critical for determining the initial reactants required for the synthesis of the compound.
