**Title: Understanding the Reaction Between an Acetylenic Anion and an Alkyl Halide****Objective:** Learn to draw the structure of the major organic product(s) for the reaction between an acetylenic anion and an alkyl halide. The reaction stoichiometry is 1:1.**Chemical Equation:**- Reactants: - Sodium acetylide ion $(\text{Na}^+:\text{C}\equiv\text{C-CH}_3)$ - Alkyl halide (1-bromo-2-methylpropane)**Reaction Mechanism:**The acetylenic anion acts as a nucleophile, replacing the bromine atom in the alkyl halide via an SN2 reaction mechanism. This forms a new carbon-carbon bond.**Product:**A compound with an extended carbon chain containing the alkyne group is formed:- The drawn structure depicts an alkyne chain connected to a branching alkyl group. The alkyl group is attached at the secondary carbon, showcasing the characteristic zigzag pattern of a carbon-carbon triple bond.**Summary:**This exercise emphasizes the formation of a carbon-carbon bond through nucleophilic substitution. It provides valuable insight into the manipulation of organic compounds using acetylenic anions in synthetic chemistry.

Diol

In chemistry there are so many chemical compounds that have a hydroxyl group but a chemical compound having two hydroxyl groups (-OH) is termed as a diol. It also implies the presence of two alcohols whereas polyols contain two or more than two hydroxyl groups (-OH). Glycol or 1,2-diol is an aliphatic diol that has two alcohol groups on adjacent carbon atoms. In industries, the most commonly used diol is ethylene glycol.

Question

**Title: Understanding the Reaction Between an Acetylenic Anion and an Alkyl Halide**

**Objective:**
Learn to draw the structure of the major organic product(s) for the reaction between an acetylenic anion and an alkyl halide. The reaction stoichiometry is 1:1.

**Chemical Equation:**
- Reactants:
- Sodium acetylide ion $(\text{Na}^+:\text{C}\equiv\text{C-CH}_3)$
- Alkyl halide (1-bromo-2-methylpropane)

**Reaction Mechanism:**
The acetylenic anion acts as a nucleophile, replacing the bromine atom in the alkyl halide via an SN2 reaction mechanism. This forms a new carbon-carbon bond.

**Product:**
A compound with an extended carbon chain containing the alkyne group is formed:
- The drawn structure depicts an alkyne chain connected to a branching alkyl group. The alkyl group is attached at the secondary carbon, showcasing the characteristic zigzag pattern of a carbon-carbon triple bond.

**Summary:**
This exercise emphasizes the formation of a carbon-carbon bond through nucleophilic substitution. It provides valuable insight into the manipulation of organic compounds using acetylenic anions in synthetic chemistry.
