Question
**Reaction Between Acetylene and Sodium Amide** The chemical equation presented illustrates the reaction of acetylene (C₂H₂) with sodium amide (NaNH₂). The equation is shown as follows: - **Reactants:** - Acetylene (C₂H₂) represented with a triple bond between the two carbon atoms. - Sodium amide, depicted as Na⁺ and the amide ion (:NH₂⁻). The nitrogen in the amide ion has a lone pair of electrons. - **Reaction:** - The equation shows an equilibrium arrow, indicating a reversible reaction. - **Product:** - The product is not explicitly shown in the diagram; however, the box on the right side is designated for the resulting species of the reaction. This reaction typically results in the formation of sodium acetylide (NaC≡CH) and releases ammonia (NH₃) as a by-product. Sodium acetylide is formed when the acidic hydrogen of acetylene is replaced by a sodium ion.

### Chemical Reactions Overview This section explores four chemical reactions featuring organic and inorganic compounds. Each reaction showcases different bond formations and charge distributions. #### a) Reaction 1: - **Reactants:** Hydrogen cyanide (HC≡N-H) and Sodium hydride (NaH). - The hydrogen cyanide features a triple bond between carbon and nitrogen. Nitrogen has a lone pair, while sodium hydride is a compound of sodium and hydrogen. #### b) Reaction 2: - **Reactants:** Ethylene (H2C=CH2) and Sodium azide (Na3N). - Ethylene has a double bond between two carbon atoms, with each carbon atom bonded to two hydrogen atoms. Sodium azide consists of sodium ions paired with azide anions. #### c) Reaction 3: - **Reactants:** Propene anion and Ammonia (NH3). - The propene anion (H2C-CH-) has an additional electron represented by a lone pair and a negative charge on one of the carbon atoms. Ammonia is a nitrogen atom with three hydrogens and a lone pair. #### d) Reaction 4: - **Reactants:** Acetylene anion (HC≡C⁻) and Ammonium ion (NH4⁺). - Acetylene anion features a triple bond between carbons, with one carrying a negative charge. The ammonium ion is a positively charged nitrogen with four hydrogens. Each reaction illustrates fundamental principles of organic chemistry, including bond types and electron configurations.
