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...
