BCH4024 Exam 1 Purich Questions & Answers 2023/2024 Basic Structure of water - ANSWER--large dipole moment -very polar that interactions between H2O molecules are strong--high heat capacity -liquid water=H-bonds are relentlessly made and broken; thus a flickering collection of W5 structures, with extremely little W1 -each water molecule can form up to 4 H-bonds -liquid water has 3.4 H-bonds on average -ice has 4 H-bonds H-bond - ANSWER-stable interaction occurring when 2 EN atoms shar...

Intermolecular forces (IMFs) correct answer: the forces of attraction between molecules of covalent compounds (weak) Intramolecular forces correct answer: forces within molecules. Forces caused by the attraction and repulsion of charged particles (strong) Dispersion forces correct answer: present in all molecules attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest inter...
