Question

Why giant molecules does not have weak Van der Waals force?

Answer 1

The more the number of molecules the stronger the bond

Answer 2

Van der waals forces in giant molecules

Explanation:

• Covalent network solids include materials such as diamond, silicon carbide, and boron nitride. Because there are no simple, distinct molecules in these materials, the topic of intermolecular attractive forces does not arise.
• Strong covalent connections connect each atom to three or four other atoms in a continuous, three-dimensional pattern. The entire crystal piece must be regarded as a single massive molecule.
• These solids' extremely high melting temperatures are owing to the strong covalent connections that exist between the atoms that make up the network, not to any kind of intermolecular attraction.
• In a nutshell, larger molecules have more electron and are more influenced by LDFs than smaller molecules with less electron.
• In the case of alkanes, the number of atoms in a molecule increases as the molecular mass increases, resulting in an increase in the chain length of molecules.
• The London Dispersion Forces are stronger in a molecule with a long chain length.
• The reason for this is that longer molecules have more points of attraction with other molecules. This is why pentane (a molecule with a longer chain) has larger intermolecular forces of attraction than methane.
• Because alkanes are non-polar, only London Dispersion Forces will be observed.
