How does increasing chain length alter the melting and boiling temperatures?

For a substance to melt or boil, heat energy must be supplied. This is to overcome Van der Waals forces. As the length of a chain increases, there are more Van der Waals forces present due to the chain ge...

Explain: 1. Why butanoic acid has a higher boiling point than butan1-ol? 2. Why carboxylic acids of short chain length are more soluble in water than those with longer carbon chain length?

1.Butanoic acid has stronger intermolecular forces (hydrogen bonding) because it has two highly electronegative oxygen atoms in its structure, whereas butan-1-ol has only one. Therefore t...
