Molecular bonds - Study guides, Class notes & Summaries

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

Chem 219 Unit 5 Exam with Correct Solutions Generic formula for alcohols - Answer -R-OH phenol - Answer -hydroxy-substituted aromatic molecules (any compound with an -OH attached to a benzene ring) IUPAC system rules for naming organic alcohols - Answer -- organic alcohols are named by replacing the suffix of the parent chain of the molecule with the suffix -ol - The parent chain is numbered so as to give the hydroxyl group the lowest possible number. (examples: 1-propanol, and cyclohexan...

Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

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...

Bonds within a molecule are called intra-molecular bonds. Non-polar (type) compounds are insoluble in water. intra-molecular Correct! Non-polar Correct! Question 2 10 / 10 pts Fill in the blanks: Pentane is insoluble in water because it is a/an nonpolar (type) compound. Ethyl alcohol has a boiling point of 76.4 C and n-propyl chloride has a lower boiling point of 46.3 C because the Hydrogen bonds holding ethyl alcohol together are stronger than the nonpolar bonds which hold n-propyl chl...
