Question
### Chemical Reaction Problems #### Problem p. - **Reactant**: A linear alkyne compound - **Reagent**: \( \text{Cl}_2 \, (\text{excess}) \) - **Description**: The alkyne undergoes halogenation with excess chlorine. #### Problem q. - **Reactant**: A branched alkyne - **Reagent**: \( \text{Br}_2 \) - **Description**: The alkyne is treated with bromine for halogenation. #### Problem r. - **Reactant**: An internal alkyne - **Reagents**: 1. \( \text{NaNH}_2 \) 2. \( \text{CH}_3\text{Br} \) - **Description**: The alkyne undergoes deprotonation with sodium amide, followed by alkylation using methyl bromide. #### Problem s. - **Reactant**: A branched alkyne - **Reagent**: \( \text{Cl}_2 \, (\text{excess}) \) - **Description**: Halogenation of the alkyne using an excess of chlorine. #### Problem t. - **Reactant**: A linear alkyne - **Reagents**: 1. \( \text{NaNH}_2 \) 2. \( \text{BrCH}_2CH_3 \) - **Description**: The alkyne is first treated with sodium amide for deprotonation, followed by alkylation using bromoethane.
