Simple molecules and covalent bonds outcomes5 objectives
- Identify that a covalent bond occurs when two atoms share a pair of electrons, resulting in electronic configurations similar to noble gases.
- Explain how covalent bonds are formed in simple molecules such as H₂, CH₄, H₂O, I₂, NH₃, and CCl₄, using dot-and-cross diagrams to illustrate their electronic configurations.
- Discuss the properties of simple molecular compounds in relation to their structure and bonding, focusing on (a) their low melting and boiling points and (b) their poor electrical conductivity.
- Illustrate the formation of covalent bonds in simple molecules such as CH₃OH, C₂H₄, O₂, CO₂, and N₂, using dot-and-cross diagrams to represent their electronic configurations.
- Clarify the properties of simple molecular compounds in terms of their structure and bonding, explaining (a) low melting and boiling points due to weak intermolecular forces and (b) poor electrical conductivity.
