Which of the following would NOT be a factor for a solute to dissolve in water?

A. A solute separates into ions which are supported by hydration.
B. Electrostatic attraction between the partially charged atoms in water molecules and the solute.
C. A solute has a higher formula weight than water.
D. A solute contains a molecular dipole.
E. All of these are factors.

i am pretty sure it is C but not positive.

You are right.

To determine which of the options would NOT be a factor for a solute to dissolve in water, let's analyze each option:

A. A solute separates into ions which are supported by hydration.
This option states that when a solute dissolves in water, it separates into ions that are surrounded and stabilized by water molecules through hydration. This process, known as solvation, is a key factor in dissolving solutes in water. Therefore, this option is a factor for solute dissolution.

B. Electrostatic attraction between the partially charged atoms in water molecules and the solute.
This option suggests that there is an electrostatic attraction between the partially charged atoms (such as oxygen and hydrogen) in water molecules and the solute. This attraction helps solutes dissolve in water. Hence, it is a factor for solute dissolution.

C. A solute has a higher formula weight than water.
This option states that the solute's formula weight (molecular weight) is higher than that of water. However, the molecular weight of a solute is generally not a deciding factor for its solubility in water. There are numerous factors involved, such as molecular structure and polarity. Therefore, this option is likely the correct answer as it does not correlate directly with solute dissolution in water.

D. A solute contains a molecular dipole.
This option claims that a solute possesses a molecular dipole, which refers to an uneven distribution of charge within the molecule resulting in partially positive and negative regions. A molecular dipole can enhance solute-water interactions and promote solubility. Thus, this option is also a factor for solute dissolution.

E. All of these are factors.
This option implies that all the previous options (A, B, C, D) are factors for solute dissolution. If any of the previous options are determined to be incorrect, then this option is not the correct answer.

Considering the analysis, option C, a solute having a higher formula weight than water, is the most likely correct answer as it does not directly contribute to the solute's solubility in water.
