← ScienceWhich consequence results when molecular dipole interactions weaken in isobutane?
A)Reduced boiling point occurs✓
B)Increased viscosity manifests itself
C)Elevated flash point exists
D)Azeotrope formation becomes probable
💡 Explanation
Weakening dipole interaction lowers the intermolecular forces, because dispersion forces (van der Waals) become weaker. Therefore the boiling point decreases, rather than increasing or forming azeotropes, because these phenomena require stronger intermolecular bonding.
