Chem 1LD - Project 1 Set with correct answers 100% 2026 Will a solute dissolve in a solvent? - Correct Answer "Like dissolves like" What does "Like dissolve like" mean? - Correct Answer To understand this statement, we have tounderstand the IMF of solute and solvent - the IMF must be alike to form a solution. What principle topic is necessary to understand intermolecular forces? - Correct Answer Electrostatic attraction What principle topic is necessary to understand Electrostatic Attraction? - Correct Answer Molecular Dipoles (Vectors) What principle topics are necessary to understand Molecular Dipoles (vectors)? - Correct Answer Molecular Geometry and Bond Dipoles What theory is necessary to determine molecular geomtery? - Correct Answer VSEPR (Valence shell electron pair repulsion) Theory What concept is necessary to predict Bond Dipoles? - Correct Answer Electronegativity Bond dipoles, in conjunction with ____________ are responsible for molecular _______. - Correct Answer Bond dipoles, in conjunction with molecular shape are responsible for molecular polarity. What dictates IMF? - Correct Answer Molecular polarity Electronegativity - Correct Answer An atom's ability to attract shared e- to itself Dipole - Correct Answer partial positive charge (sigma+) next to a partial negative charge (sigma-) Vector - Correct Answer A quantity that has magnitude and direction How do you represent a dipole using a vector? - Correct Answer The partial positive charge is represented by a cross on one end while the partial negative charge is indicated by the tip of the arrow (you can think of this as being the directional pull of electrons by the electronegative atom) How do bonds become polar? - Correct Answer The difference in electronegativity of two bound atoms causes a bond dipole. The greater the difference in electronegativity, the more polar the bond. Draw a figure representing the gradiant of polarity of different types of bonds: Nonpolar covalent bonds, Polar covalent bonds, and Ionic bonds - Correct Answer ---- increasing polarity nonpolar covalent bonds (ex. H-P or H-C), polar covalent bonds (ex. H-Cl, H-O, H-F), ionic bonds (ex. Na+F-) - Correct Answer Molecular dipoles are the summation of... - Correct Answer Molecular shape + bond dipoles How do you find a molecular dipole - Correct Answer Draw the lewis structure Use VSEPR to determine molecular shape - Correct Answer Use electronegativity to determine bond dipoles - Correct Answer
