The boiling point depends on the strength of the intermolecular forces holding the molecules together. Greater the force, higher is the boiling point.

The intermolecular force increases in the order shown below:

ion-ion > H-bonding > dipole-dipole > London dispersion

CH3CN is a polar molecule with strong dipole-dipole forces

CH3CH2CH3 is non-polar held by london dispersion

Ar exist as a gas. It will have a lowest boiling point

Thus the order of decreasing b.pt is:

CH3CN > CH3CH2CH3 > Ar

Valence electrons<br> Fill in the blanks
IgorC [24]

Answer:

Valence electrons or outer electrons are most important as they participate in bonding. The octet rule states that atoms gain, lose, or share valence electrons to have filled energy levels.. this gives atoms a stable configuration like that of the nearest noble gas.

Your question has been heard loud and clear.

Both scientific laws and scientific theories are not based on hypothesis.

Because , scientific laws are proven and so they are real not hypothetical.

Whereas scientifc theories can be hypothetical.

Thank you

A potassium atom (atomic number 19) and a bromine atom (atomic number 35) can form a chemical bond through a transfer of one ele
liubo4ka [24]

Answer:

A potassium atom (atomic number 19) and a bromine atom (atomic number 35) can form a chemical bond through a transfer of one electron. The potassium ion that forms has 18 electrons. What best describes the bromide ion that forms? It is a negative ion that has one more valence electron than a neutral bromine atom.
