Question

I want to confirm some things on solubility and boiling points(they might be right or wrong):

- If a substance is soluble in water then it also has a high boiling point

- If a substance has a high intermolecular force then it also has a high boiling point

- Shorter carbohydrate chains are more soluble in water than long carbohydrate chains

- Chains with more shielding (more side chains) has a lower solubility in water

- Every molecule has london-dispersion force

I would also like to know the difference between Vann Der Waals Forces and intermolecular forces
- If a substance is soluble in water then it also has a high boiling point
<b>High is a relative word; I don't know how to answer this.</b>

- If a substance has a high intermolecular force then it also has a high boiling point
<b>Same point here</b>

- Shorter carbohydrate chains are more soluble in water than long carbohydrate chains
<b> This is true</b>

- Chains with more shielding (more side chains) has a lower solubility in water
<b> true</b>

- Every molecule has london-dispersion force
<b>true</b>

I would also like to know the difference between Vann Der Waals Forces and intermolecular forces
<b>Here is a site to read.
