Question

methanol, ch₃oh, dissolves completely in water to form a solution that does not conduct electricity. which of the following diagrams best shows the major type of attractive force that exists between the particles in the solution?

Explanation:

Step1: Identify the key concept

Methanol ($CH_3OH$) and water are polar - molecules. The major attractive force between them is hydrogen - bonding. Hydrogen - bonding occurs when a hydrogen atom is bonded to a highly electronegative atom (such as O, N, or F) and is attracted to another electronegative atom.

Step2: Analyze each option

In option A, the hydrogen - bonding is correctly represented between the oxygen of methanol and the hydrogen of water. In option B, the charge distribution in the hydrogen - bonding representation is incorrect. In option C, the orientation and the way of showing the hydrogen - bonding is not the most accurate representation of the interaction between methanol and water molecules.

Answer:

A.
