Question
Which type of crystal is composed of repeating units of nonpolar molecules held together by weak intermolecular forces?Select one:a.covalent crystalb.molecular crystalc.ionic crystald.metallic crystal
Solution
The type of crystal composed of repeating units of nonpolar molecules held together by weak intermolecular forces is a molecular crystal.
Here's a step-by-step explanation:
-
Covalent crystals are composed of atoms held together in a lattice structure by covalent bonds, which are very strong intermolecular forces.
-
Molecular crystals are composed of molecules held together by weaker intermolecular forces, such as London dispersion forces, dipole-dipole interactions, and hydrogen bonds. Nonpolar molecules, which have no net electrical charge, are held together by London dispersion forces, the weakest type of
