The stronger the intermolecular forces, the higher the viscosity.<\/p>\n\n\n\n<p>Let&#8217;s analyze the given options:<\/p>\n\n\n\n<p><strong>A) (CH3CH2)2CO (Diethyl ketone)<\/strong><br>This is a ketone, where the only intermolecular forces are dipole-dipole interactions and van der Waals forces. The dipole-dipole forces are moderately strong, but not as strong as hydrogen bonding.<\/p>\n\n\n\n<p><strong>B) C2H4Cl2 (1,2-dichloroethane)<\/strong><br>This is a halogenated hydrocarbon. The primary intermolecular forces are dipole-dipole interactions due to the electronegativity difference between chlorine and carbon. However, halogenated compounds generally have relatively low viscosity compared to those capable of hydrogen bonding.<\/p>\n\n\n\n<p><strong>C) HOCH2CH2CH2CH2OH (1,4-butanediol)<\/strong><br>This molecule contains two hydroxyl (OH) groups capable of hydrogen bonding. Hydrogen bonding is a very strong intermolecular force, which leads to higher viscosity. The presence of two OH groups increases the ability to form hydrogen bonds, making 1,4-butanediol much more viscous than other molecules in the list.<\/p>\n\n\n\n<p><strong>D) CF4 (Carbon tetrafluoride)<\/strong><br>This molecule is nonpolar, and its primary intermolecular force is London dispersion forces (induced dipole-induced dipole forces), which are weak. As a result, CF4 has a very low viscosity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>1,4-butanediol (C) has the highest viscosity due to the strong hydrogen bonding between its OH groups. The other substances have weaker intermolecular forces, leading to lower viscosity.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1418.jpeg\" alt=\"\" class=\"wp-image-264948\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Choose the substance with the highest viscosity.
