The addition reaction is a chemical reaction that occurs between two or more reactants and produces a single product. This reaction is characterized by the addition of a functional group to another, the latter usually being an alkene. Which of the following substances is an alkene?

Organic salts are compounds derived from the reaction of an inorganic base with a carboxylic acid. These compounds have distinct characteristics from inorganic salts, such as solubility in organic solvents and soap and detergent properties. A classic example of an organic salt is sodium acetate, which can be obtained by the reaction of acetic acid with sodium hydroxide. Given the formula of acetic acid (CH3COOH), identify the inorganic base that, when reacting with acetic acid, forms sodium acetate. This reaction is an example of:

When studying covalent bonds, 1st-year high school students learned about Lewis theory, which describes the formation of covalent bonds through the sharing of electron pairs between atoms. Considering that the covalent bond is formed between two non-metals, propose and explain an example of a covalent compound, highlighting its structural formula and how Lewis theory can be applied to describe the formation of covalent bonds in the chosen compound. Additionally, briefly discuss a characteristic physical or chemical property of this type of covalent compound that differentiates it from ionic or metallic compounds.
