Question

Which answer best completes the following sentence?

_________________ bonding exists within the same molecule, and _____________ forces exist between different molecules.


Hydrogen, ionic

Ionic, covalent

Intermolecular, London dispersion<--- my answer, correct?

Ionic and covalent, intermolecular

Answer 1

Yes, the answer you picked (C./ 3rd) is correct. The inside (inter) and LDF are outside. :)

Answer 2

Answer:

Intermolecular, London dispersion

Explanation:

(a) Hydrogen bonding can exist between same molecule and different molecules, so not the answer.

(b) and (d) Covalent bonding can exist in same elements like N₂ and also in different like CO₂ and not the answer.

(c) Intermolecular forces are forces that mediate the interaction between the same molecules.

London dispersion force is temporary attractive force which results when electrons in the two adjacent molecules occupy the positions which make them a temporary dipoles. It happens between different molecules.

hence, it is correct.
