3.4.1—Covalent bonding examples question 1
[Maximum number: 1]
The strength of interaction between particles determines whether the substance is a solid, liquid or gas at room temperature.
Carbon monoxide, CO, is a gas at room temperature and pressure. It contains a coordinate bond.
Explain what is meant by coordinate bond.
(covalent) bond with both electrons are provided from the same / one species
OR
shared pair (of electrons) are provided from the same species / one atom owtte
