which substance most likely has the highest boiling point?\ncalcium chloride (cacl₂), an ionic compound\nmethanol (ch₃oh), a polar covalent compound\ncarbon tetrachloride (ccl₄), a nonpolar covalent compound
Answer
# Brief Explanations:
Ionic compounds have strong electrostatic forces (ionic bonds) between ions. Polar covalent compounds have dipole - dipole forces and hydrogen bonding (in methanol, due to - OH group), but these are weaker than ionic bonds. Non - polar covalent compounds have only London dispersion forces, which are the weakest among the three types of intermolecular/intramolecular forces considered here. Stronger forces require more energy to break, resulting in a higher boiling point.
# Answer:
calcium chloride (\(\ce{CaCl2}\)), an ionic compound
