What is the difference between a polar bond and a polar molecule?
A polar bond occurs when there is an unequal sharing of electrons between two atoms in a molecule, creating a partial positive and partial negative charge. A polar molecule, on the other hand, is a molecule that has an overall uneven distribution of electron density, resulting in a positive and negative end. In summary, a polar bond refers to the relationship between two atoms, while a polar molecule describes the entire molecule as a whole.
In the plasma membrane why is the nonpolar attracted when opposites are supposed to attract ie polar and nonpolar?
I can only answer the second part of your question. As far as attraction goes, polar is not the opposite of nonpolar. Polar in itself has two opposites: positive and negative. Those two are the opposites that attract; a positive region of a polar molecule is attracted to the negative region of another polar molecule.
What is a molecule that has a partial positive charge on one end and a partial negative charge on the other?
A polar molecule...such as water. The oxygen molecules pulls the electrons closer, causing the oxygen to have a more negative charge and the two hydrogen atoms to have more positive charges. this is very important in the bonding of water molecules to other water molecules.
What does it mean when a molecule is said to be polar?
A polar molecule is one in which the distribution of electrons is uneven, resulting in partial positive and negative charges within the molecule. This creates a separation of charge, with one side being slightly positive and the other slightly negative. Examples of polar molecules include water (H2O) and ammonia (NH3).
Molecule that has a slightly positive end and a slightly negative end?
A polar molecule. The charges are signified using δ± (delta meaning a difference or change, lowercase meaning it is a small difference, the ± denoting whether that end is positive or negative).If the same molecule contains both positively and negatively charged groups, it's called a zwitterion.A molecule having both slightly negative and positive ends is a polar molecule.
Why is a water molecle polar?
Water is polar due to the two sets of unbound electron pairs on the oxygen molecule which oppose the positivly charged hydrogen. This causes a dipole, a positive and negative end to the molecule.
The equal but opposite charges present in the two regions of a polar molecule create?
The equal but opposite charges present in the two regions of a polar molecule create a dipole moment, leading to the molecule having both a positive and a negative pole. This results in the molecule being attracted to other polar molecules through intermolecular forces such as hydrogen bonding.
Is H2O a nonpolar molecule?
No, H2O is a polar molecule. The oxygen atom in H2O is more electronegative than the hydrogen atoms, causing a partial negative charge on the oxygen and partial positive charges on the hydrogen atoms. This separation of charge results in a polar molecule.
Carbon dioxide with its two double bonds is an example of an nonpolar molecule.?
true
Why is CH2Cl2 polar?
CH2Cl2 is polar because it has a symmetrical tetrahedral shape with two hydrogen atoms and two chlorine atoms, resulting in an unequal distribution of charge within the molecule. This causes a separation of positive and negative charges, making it polar.
Is iodine polar or non polar?
An iodine molecule is formed by two 'I' atoms. It implies that the molecule is symmetrical and it is non-polar.
Is oxygen molecules polar?
No. A non-polar molecule is one that the electrons are distributed more symmetrically and thus does not have an abundance of charges at the opposite sides. Oxygen molecule O2 is formed with two of the same atom. The electrons are distributed more symmetrically. Therefore, O2 is a non-polar molecule. See more explanation at related link
