What do you mean by Dipole Moment and Induced Dipole Moment?
Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces. An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.
What characteristics of the water molecule allows it to play an extensive role in many biological reactions?
It's a polar molecule: a molecule that has a net dipole moment due to its having unsymmetrical polar bonds. Unequal sharing of electrons makes water a polar molecule.
What are polarized molecules?
Water is one of them
What is dipolar nature of water?
A dipole refers to two electrostatic charges which are separated by distance. In chemical compounds a dipole refers to unequal distribution of charge across a molecule that leads to an effective dipole often due to vector sum of bond dipoles.
Does water have permanent dipole?
Yes, water shows all three types of common intermolecular forces, namely dispersion forces, dipole-dipole forces and hydrogen bonds. Dispersion forces are present at any species which consists of movable charges that can be shifted with respect to one another. Thus a dipole emerges which on his part can induce dipoles in close-by molecules. The permanent dipole of water molecules leads to dipole-dipole forces. They can be distinguished from hydrogen bonds as they are present even at angles where no significant hydrogen bonds are expected any more.
The OH bonds in water molecule are polar. The molecule is symmetric and the HOH bond angle is approximately 107 degree. The dipole moment vector of the molecule is?
From a physical standpoint, the dipole moment vector of a molecule is the net electric static force between the atoms. Assuming the molecule to be symmetrical, the vectors from the hydrogens toward the oxygen will cancel in the x-direction, leaving only a vector going from the center of the two hydrogens toward the oxygen.
Is H2o a dipole force?
Yes it is. there are lone pairs on the oxygen that induce the dipole moment
Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
Water is a polar molecule because?
Oxygen is more electronegative than hydrogen and creates a dipole moment.
The water molecule has a dipole with the negative portion?
Water (H20) is a polar covalent molecule with two highly electronegative oxygen atoms. The electronegative oxygen atoms create a dipole moment, and are also cause H20s bent shape.
What is an ion-dipole bond?
An ion-dipole force is just how it sounds, an ion meets a molecule with a permanent electric dipole moment. An example would be Na+ with water, or Cl- with water, in an aqueous solution of NaCl.

Using intermolecular forces explain why water is a liquid at room temperature but ammonia is a gas.?
The simplest answer is polarity. As I'm sure you know, both water and ammonia form hydrogen bonds with like molecules. But the critical difference is that water is a polar molecule and has a dipole moment, whereas ammonia is non-polar and does not have a dipole moment. A dipole moment is the result of polar bonds. It is important to note that having polar bonds DOES NOT necessarily make a molecule polar. Imagine that the bonds on a molecule pushes the nucleus in the direction of the bond. In a molecule with all of its bonds evenly spaced and of the same type (Hydrogen to Nitrogen, for example), such as in NH3, all of the bonds cancel each other out. But in a molecule with its bonds unevenly spaced, such as in H2O, the bonds do not cancel each other out, resulting in a dipole moment.
Why carbon dioxide have no dipole moment but water have some dipole moment?
Carbon dioxide is a linear molecule and any charges on the oxygens cancel each other out. emember vectors? Water is not linear the bent shape means that the charges on the H atoms do no cancel each other.
