As it cools off, olive oil slowly hardens and forms a solid over a range of temperatures. Which best describes it as a solid?
A
Ionic
B
Covalent Network
C
Metallic
D
Amorphous
E
Molecular Crystals
Verified step by step guidance1
Understand the types of solids: Ionic solids are composed of ions and have high melting points. Covalent network solids consist of atoms connected by covalent bonds in a continuous network. Metallic solids are composed of metal atoms with a 'sea of electrons'. Amorphous solids lack a well-defined structure.
Recognize that olive oil is an organic compound primarily composed of triglycerides, which are large molecules.
Identify that molecular crystals are solids where the lattice points are occupied by molecules held together by intermolecular forces such as van der Waals forces, hydrogen bonds, or dipole-dipole interactions.
Consider the properties of olive oil: it hardens over a range of temperatures, indicating that it does not have a sharp melting point, which is characteristic of molecular crystals.
Conclude that olive oil, when solidified, is best described as a molecular crystal due to its composition and the nature of its solid state.
