Examples: stearic acid, hydrofluoric acid.
Nucleic acids would be one example of a covalent compound with more than 3 elements. Proteins have more than 3 elements as well. Many organic compounds do, it is quite common.
They form both. For example, the standard alkyls, alcohols, acids, amines, aminos, etc. form covalent bonds, but organometallic compounds, salts of acids and amines, and similar compounds form ionic (although still using covalent bonding for part of thir structure).
No. Covalent substances do not conduct electricity in solid or liquid state.
Covalent compounds composed of carbon-based molecules include hydrocarbons (such as methane, ethane, and benzene), alcohols (such as ethanol and methanol), acids (such as acetic acid), and amino acids (such as glycine and alanine). These compounds are characterized by carbon atoms forming covalent bonds with hydrogen, oxygen, nitrogen, and other elements.
Acids are not typically considered ionic compounds. Acids are usually covalent compounds that contain hydrogen ions. When acids dissolve in water, they release hydrogen ions (H+) and form hydronium ions (H3O+), which gives them their characteristic acidic properties.
Covalent compounds can be found in a variety of foods, such as fruits, vegetables, grains, and proteins. For example, carbohydrates like glucose and fructose have covalent bonds, as well as lipids like fats and oils. Proteins, which are made up of amino acids, also contain covalent bonds.
Covalent compounds are usually composed of two or more non-metal elements bonded together by sharing electrons. This sharing of electrons creates a stable electron configuration for each atom involved in the bond.
No, not all acids are covalent. Acids can be classified as either covalent or mineral acids based on their chemical composition. Covalent acids contain hydrogen and a nonmetal element, while mineral acids typically contain hydrogen and a metal.
For example, ionic compounds: inorganic acids, salts, bases; many organic compounds, etc.
No, wax contains very large molecules.
They are not always inorganic. For example, benzoic acid, ethanoic acid and ascorbic acid (vitamin c) are all organic compounds. However, acids and bases are generally ionic compounds when in solution. This is because the definition of an acid , as well as something with a pH of less than 7, can be "a substance that can form ions, the only positive ion present being the Hydrogen H+ ion". Similarly a base is the oxide or hydroxide of a metal (or something acting like a metal such as the ammonium ion). Bases that dissolve in water react with the water to form alkalis which have, as their only negative ions, hydroxide ions (OH-). Therefore, all acids and bases must be ionic compounds rather than covalent compounds as they need to form ions in solution. Furthermore, there are many acids that are covalent (such as the organic acids above) and only become acids when in solution. Such an example is thanoic acid which is a covalent compound: CH3COOH. This is not acidic unless it is in the presence of water, when it becomes an acid splitting into ions: CH3COOH -----------> CH3COO- + H+
Acids react -in most cases, but not exclusively- well with basic (alkaline) compounds.
