For bent molecular geometry when the electron-pair geometry is tetrahedral the bond angle is around 105 degrees.
Keeping this in view, what is the degree of a bent molecule?
Water (H2O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°.

Furthermore, is no2 linear or bent? NO2 is a bent molecule; however, when you remove an electron from it, making it NO2+, the molecule becomes linear due to the loss of a lone electron. On the other hand, nitrogen dioxide, NO2, is an AX2E species, and it has an angle of 134 degrees. The additional lone pair on the SF2 molecule makes the angle smaller.
Beside above, what are the two possible bond angles for a molecule with a bent shape?
The two hydrogen atoms and the two lone electron pairs are as far apart as possible at nearly 109o bond angle. This is tetrahedral electron pair geometry. The 2 lone electron pairs exerts a little extra repulsion on the two bonding hydrogen atoms to create a slight compression to a 104obond angle.
Why is a molecule bent?
The reason water has a bent shape is that the two lone pair of electrons are on the same side of the molecule. This repulsion of the lone pairs of electrons on the oxygen atom causes the bond of the hydrogen to the oxygen to be pushed downward (or upward, depending on your point of view).
Similar Question and The Answer
Is ch4 bent?
If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H2O). Five electron pairs give a starting point that is a trigonal bipyramidal structure.
Is a bent molecule polar?
The symmetric shapes are linear, trigonal planar, and tetrahedral. The unsymmetric shapes are bent and trigonal pyramidal. The symmetric shapes are associated with molecules whose central atoms have no lone pairs. If there is more than one kind of atom attached to the central atom, the molecule is polar.
What is the difference between bent and linear?
Linear = is just a line of atoms with a 180° angle. Notice that it's 2 or 3 atoms total. Bent = Linear but bent due to the Lone Pairs that it contains, the more Lone Pairs the greater the bent and the smaller the degree.
Is water Polar?
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
Why is co2 linear and not bent?
Carbon Dioxide the Lewis diagram shows carbon at the center with no lone electron pairs. The carbon and and both oxygen are bonded through double bonds which counts as "two electron pairs". Hence the molecule has two electron pairs and is linear.
How is polarity defined?
In chemistry, polarity refers to the way in which atoms bond with each other. When atoms come together in chemical bonding, they share electrons. A polar molecule arises when one of the atoms exerts a stronger attractive force on the electrons in the bond.
Is water tetrahedral or bent?
An example of bent molecular geometry that results from tetrahedral electron pair geometry is H2O. The water molecule is so common that it is wise to just memorize that water is a BENT molecule. The oxygen has 6 valence electrons and thus needs 2 more electrons from 2 hydrogen atoms to complete its octet.
How do you predict molecular shapes?
To predict the shape of a molecule: Write the Lewis dot structure for the molecule. Determine the steric number of the central atom. Decide on the electron pair orientation based on the steric number. Consider the placement of lone pairs and any distortions from "regular" shapes.
How do you know when a molecule is bent?
You would know the molecule is bent if it has any lone pairs. In the case of water, although it has two bonds that are connected to the H, it also has two lone pairs which push down on the two bonds and make a "bent" shape rather than it being linear.
