How do you use shapes to predict molecular polarity?
if molecular shape is symmatrical then its non-polar but if it is non symmatrical then its polar.
How does molecular shape effect polarity?
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
How do you know if a molecular compound has a dipole-dipole attraction?
A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.
Is IF polar or non polar?
Intermittent fasting (IF) is a dietary pattern and not a chemical compound, so it does not have a molecular structure that determines its polarity.
Which two physical properties allow a mixture to be separated by chromatography?
Size and shape. However, chemical properties are usually more important.
