Acetone evaporates more quickly than water at room temperature. what can you say about the relative strenth of the intermolecular forces in the tow compounds? which substance is more volatile?

Explanation:

Volatility means the ability of a substance to readily evaporate into the atmosphere.

In water, there is hydrogen bonding which is stronger in nature. As a result, molecules of water are held tightly with each other. So, more heat is required to break these bonds.

Hence, water has higher boiling point than acetone.

Whereas in acetone, molecules are held by weak intermolecular forces. As a result, bonding between the molecules of acetone is weak. So, this bonding can be broken down by slight heating.

As a result, acetone readily evaporates into the atmosphere. Hence, acetone is more volatile than water.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

it is the most commonly accepted one
