Web26 mrt. 2024 · Answer to Question #175813 in General Chemistry for Nicole. An ion-dipole force is an attractive force that results from the electrostatic attraction between an ion and a neutral molecule that has a dipole. 1. WebThe molecular ion peak is the peak with the largest mass-to-charge ratio after excluding any peaks caused by the presence of heavier isotopes. The base peak in a mass spectrum is the most intense (tallest) peak attributable to the ion with the largest relative abundance (relative intensity; peak height along the y-axis).

WebIon-dipole forces describe the electrostatic attraction between an ion and a neutral molecule with a dipole. The ion will attract one side of the dipole and repel the other. Dipoles in polar molecules are caused by a difference in electronegativities greater than 0.4. The formula for the ion-dipole potential is: \( E = \frac{ -k q_1 \mu } {r ...
