Why is of2 polar

As the shape is bent now, both these dipole moments are not canceled out. Instead, the dipole moments will sum up, making this molecule a polar molecule. As the dipole moments are not canceled out in the OF2 molecule , there will be a net dipole moment in it, which means there will be partial negative charges and partial positive charges in the molecule.

Thus Oxygen Difluoride or OF2 is a polar molecule. Your email address will not be published. February 3, Posted by Priyanka.

However its use is also limited by these oxidizing properties. OF2 is a considered a poisonous gas that rapidly reacts with many different compounds including water vapor to produce other toxic products.

Therefore it is recommended that this compound be handled with extreme caution. Labels: chemistry , Lewis Structures , Polarity , Science , zlatest. No comments:. The geometrical shape of Oxygen difluoride is similar to that of water ie; V-shaped bent structure.

The OF2 molecule has oxygen and fluorine atoms that have an electronegativity difference of around 0. Being more electronegative, the fluorine atom attracts the bonded pair of electrons slightly towards it and it gains a partial negative charge and oxygen atom gains partial positive charge. As a result, the O-F bonds ensure the dipole moment in the same direction and the net dipole moment of the whole molecule is also nonzero. There are 2 lone pairs on oxygen atom and 3 lone pairs on both fluorine atoms.

As per the VSEPR theory, the repulsion among lone pairs and bond pairs causes the distortion in shape. The asymmetric geometrical structure of a molecule makes it polar because, in these shaped molecules, the dipoles do not cancel each other. They gave resultant dipole as nonzero. More electronegative atom attracts bonded electron pairs more towards itself. The difference between the electronegativity of two atoms forming a covalent bond exhibit polarity in their bond.

Geometrical shape : If the shape of a molecule is symmetric, the molecule is nonpolar in nature because of the following reasons. The symmetrically shaped molecules in which atoms have the same electronegativity have equal charge distribution on them and are nonpolar in nature. If the symmetrical molecule has dipoles within it, then these dipoles get canceled by each other. Dipole moment : The dipole moment of a molecule is the measure of its polarity. The polarity of a molecule is directly proportional to the dipole moment of a molecule.

In the molecule of OF2, there are 20 valence electrons out of which 4 electrons participate in the covalent bonds and remaining exist on the oxygen and fluorine atoms in the form of lone pairs. The lone pairs exert force on the bonded pair electrons and bonds shift towards downward resulting in the V-shaped molecule OF2. Lewis structure of a molecule is the structure that depicts the bonding between the atoms and lone pairs on the atoms involved in the molecule.

Lone pair around central atom Oxygen : 2 Lone pair around other atoms Fluorine : 3 Molecular geometry of molecule: Bent shape. The oxygen difluoride OF2 has a bent molecular shape and also have lone pairs on Oxygen and Fluorine atoms. As per VSEPR theory, the repulsion between lone pairs on oxygen and fluorine and bonded pairs causes the shape of OF2 to turn out to V-shape or bent shape. The electronegativity of fluorine is more than that of oxygen due to which the O-F bond becomes polar.

This polarity in the O-F bond ensures some non zero dipole and due to asymmetric shape of OF2, the dipole of molecules comes out to be non zero making it a polar in nature. If you guys have any questions. You can ask them in the comment section.
