Question

Explain briefly why the student has grouped the different bonds like this?

Answer 1

Answer:

Explanation:

Intra-molecular bonds are bonds that happen within a molecule.

Covalent is obvious, atoms are sharing electrons.

With ionic, the electrons are being donated and are attracted by ionic charges.

With metallic, the anions are held together by the delocalised electrons.

Inter-molecular "bonds" happen between molecules.

Hydrogen bonds occur when hydrogen is polarized to become electropositive in a molecule due to the higher electronegativity from another atom, and then interacts with a very electronegative end of a polar molecule.

van De Waals forces occur from permanent dipoles in a molecule creating positive and negative regions.
