- Glucose can dissolve in water because the + pole on a hydrogen atom in water can:
a. Form a hydrogen bond to a – pole on an oxygen atom in glucose
b. Form a non-polar covalent bond to a – pole on an oxygen atom in glucose
c. Form a hydrogen bond to a + pole on a hydrogen atom in glucose
d. Form a hydrogen bond to a carbon atom in glucose
Homework Answers
- For a liquid to dissolve a solid, the molecules of the liquid and solid must attract one another.
- The bond between the oxygen and hydrogen atoms (O–H bond) in sugar (sucrose) gives the oxygen a slight negative charge and the hydrogen a slight positive charge. Sucrose is a polar molecule.
- The polar water molecules attract the negative and positive areas on the polar sucrose molecules which makes sucrose dissolve in water.
- Glucose can dissolve in water because the + pole on a hydrogen atom in water can form a hydrogen bond to a – pole on an oxygen atom in glucose(a).
- Thank you

Because water molecules can form a variety of hydrogen bonds
with each other, water molecules tend to have more configurations
when they are by themselves than when they are mixed with other
molecules that cannot form hydrogen bonds. Imagine that the
interactions between water molecules and the molecules of a non
polar substance A (W-A interactions) are stronger than the W-W and
A-A interactions. In this case one can predict that:

7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...

a)
The water molecule consists of two hydrogen atoms and one oxygen
atom. Since the oxygen atom has a higher electronegativity than the
hydrogen atom, the side of the molecule with the oxygen atom has a
partial negative charge.
Assume that the partial positive charge on each hydrogen atom is
Q2 = 0.512 x 10-19 C. What is the
electric charge Q1 on the Oxygen atom?
b)
The water molecule forms an angle, with hydrogen atoms at the
tips and...
