Does the The geometry of a molecule as well as the polarity of its bonds determines whether a molecule is polar or not?
Yes. Taking water, H2O, one Oxygen atom bonded to two Hydrogen atom as example) is not symmetrical( In 3-dimentions). Oxygen which is an electronegative element tends to pull electron from the Hydrogen-Oxygen bond and thus becoming a negative dipole living hydrogen as a positive dipole. so water molecule is a polar molecule. This is why when you bring a comb you just used near a slim stream of water, the stream bends toward the comb.

What determines whether a solute is hydropholic or hydrophobic?
What determines a molecule's solubility degree in water is its polarity. Equals dissolve.
Which is a factor that determines wheathe a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, such as oxygen and carbon dioxide, can easily pass through the lipid bilayer, while larger or polar molecules often require specific transport proteins to facilitate their movement. Additionally, the concentration gradient and the presence of channels or carriers also influence a molecule's ability to cross the membrane.
Any molecule that has a polar geometry is called what?
A good clue is to look at the symmetry of the molecular geometry. Molecules that are not symmetric are polar.In a bond, the more electronegative atom attracts a bigger share of the shared electrons than the other. This separation of charge results in a bond dipole. When all the bond dipoles of a molecule are added, the net dipole is called the permanent dipole moment. When the bond dipoles cancel, the molecule's dipole moment is zero and the molecule is called nonpolar. If the bond dipoles do not cancel, the molecule is polar.Lone pairs contribute to the polarity of a molecule. Since there is no positive nucleus to offset the negative charge of the lone pair, the end with the lone pair will always have a higher partial negative charge than any atom.The key to determining whether or not dipoles cancel is to consider their direction as well as their magnitude. The direction is determined by the molecular geometry. The Lewis structure does not represent the molecular geometry.
What is the other factor in whether or not a molecule is polar?
In addition to the molecule's geometry (shape), the other factor in determining whether a molecule is polar is the difference in electronegativity between the atoms that make up the molecule. If there is a significant difference in electronegativity, causing an uneven distribution of electron density, the molecule is more likely to be polar.

Is the molecule polar and hydrophilic or hydrophobic?
The polarity of a molecule determines whether it is hydrophilic (attracted to water) or hydrophobic (repelled by water). If a molecule is polar, it is typically hydrophilic, meaning it can dissolve in water. If a molecule is nonpolar, it is usually hydrophobic and does not mix well with water.
What determines whether a solute is hydropholic or hydrophobic?
What determines a molecule's solubility degree in water is its polarity. Equals dissolve.
What determines whether or not a substance will dissolve?
The most important characteristic is the polarity of the solvent and solute.
What determines whether a compound is a polar compound?
A number of factors. The polarity of the chemical bonds due to differences in electronegativity. The geometry of the moecule which may lead to these bond dipoles cancelling each other out. The contribution of a lone pair.
Is hydrophilic a property that determines whether a molecule is polar or nonpolar?
Yes, hydrophilic is a property that determines whether a molecule is polar or nonpolar. Hydrophilic molecules are polar, while hydrophobic molecules are nonpolar.
What determines whether charges attract or repel?
If charges are alike, they repel. If charges are opposite, they attract.
How does the shape of a molecule affect the polarity of a molecule?
The shape of a molecule affects polarity because of how bond dipoles between two atoms is affected by other atoms in the molecule. Bond dipoles are vector quantities (which means they have magnitude and direction), so when a molecule has two or more bond dipoles they can cancel each other out if they perfectly oppose each other. For example CO2 (O=C=O) has two dipole bonds, but since they equaly oppose each other they cancel out and the molecule is nonpolar. In bent molecules like H2O, the two hydrogens bonded to the oxygen have equal dipole moments, but they do not directly oppose each other so they do not cancel out. As a result the molecule is polar. So in summery the molecule's geometry affects the polarity of the molecule by dictating the direction of the vector quantities of the dipole bonds, which determines whether they will be able to cancel each other out (nonpolar) or allow for non zero dipole moments (polar).
