The attraction between water molecules is the result of water?
The attraction between water molecules is the result of hydrogen bonding. This occurs when the positively charged hydrogen atom in one water molecule is attracted to the negatively charged oxygen atom in another water molecule. These hydrogen bonds give water its unique properties such as high surface tension and cohesion.
The difference between polar molecuels and nonpolar molecuels?
A polar molecule in which there is some separation of charge in the chemical bonds, so that one part of the molecule has a slight positive charge and the other a slight negative charge. A common example of polar molecule is water. The water acts as a solvent for polar molecules. A non-polar molecule has no separation of charge, so no positive or negative poles are formed.
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
How easy or hard is it for polar molecules to pass through the cell membrane?
Polar molecules are effectively charged molecules. It's hard for them to cross the cell membrane because the membrane is comprised of an uncharged phospholipid bilayer. Charged molecules tend to have specific protein channels that allow them to cross the membrane.
Why do water molecules break up other polar molecules?
Water molecules break up other polar molecules through a process called hydration or solvation. The partially positive and negative charges on water molecules allow them to surround and interact with polar molecules, causing them to break apart or dissolve in water. This is due to the strong electrostatic interactions between water and polar molecules.
What is different between polar and non-polar molecules?
A polar molecule is one that has a negatively charged end and a positively charged end, which form poles. A non-polar molecule doesn't.
When the molecules are attracted to a charged wand are they polar or nonpolar?
The molecules attracted to a charged wand are most likely polar molecules. Polar molecules have uneven distribution of charge which allows them to interact with other charged objects, such as a charged wand. Nonpolar molecules have a more symmetric charge distribution and are less likely to be attracted to a charged wand.
Molecules that do not have oppositely charged ends are what molecules?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Gasoline and cooking oil are not amphipathic molecules why?
They do not have polar or charged regions.
Which type of bond forms between oppositely-charged region of polar molecules?
Hydrogen bond
What molecules forms a polar covalent bond?
In these molecules the difference of the electronegativity between the two atoms is significant.
Hydrogen bonds can form between regions of polar molecules that are?
Hydrogen bonds can form between regions of polar molecules that are partially positive and partially negative. This occurs when hydrogen atoms covalently bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine interact with neighboring atoms with a partial negative charge.
What is the difference between polar bonds and polar molecules?
Polar bonds occur when there is an unequal sharing of electrons between atoms in a molecule, resulting in a partial positive and partial negative charge. Polar molecules have an overall uneven distribution of electron density, leading to a positive and negative end. Not all polar bonds create polar molecules, but all polar molecules contain polar bonds.
What is polar and non polar compound?
polar compounds are those which have charged ends or you can say those compound or molecules which have +ve ends and -ve ends in their structure . non polar are those which don't have any charged ends thee molecules are neutral in their configuration . polar molecules have strong force of attraction than non poalr molecules between them due to which thaey have high melting point and strength
What explains the forces acting upon polar molecules?
Polar molecules have an uneven distribution of charge, resulting in partial positive and negative regions. These molecules experience attractive forces between the positively charged region of one molecule and the negatively charged region of another, known as dipole-dipole interactions. Additionally, polar molecules can also have London dispersion forces, which are weak temporary attractions between molecules due to fluctuations in electron distribution.
What happens when polar molecules are between oppositely charged metal plates?
Polar molecules are attracted to the oppositely charged metal plates due to the electrostatic forces. The molecules will align themselves with the electric field between the plates, causing the plates to exhibit slight dipole moments. This can lead to changes in the properties of the molecules, such as increased polarity or reorientation of molecular orientation.
Why PH3 and OF2 and HF are polar molecules?
due to the difference in the between the two atoms in the molecule
