Is H2O linear or tetrahedral?
tetrahedral
Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°.

Is H2O trigonal planar geometry?
D.) Trigonal planar. Hint: In water molecules there are two lone pairs on oxygen. According to VSEPR theory, there are repulsions of lone pair-lone pair repulsions, the water molecule tends to acquire bent shape or V-shape.
Is h20 linear or bent?
Water is a molecular compound consisting of polar molecules that have a bent shape. The oxygen atom acquires a partial negative charge, while the hydrogen atom acquires a partial positive charge.

What shows geometrical isomerism?
ClCH=CHCl has two different substituents on each carbon atom of double bond and hence shows geometrical isomers.
Which of the following compounds will exhibit geometrical isomerism?
Only compound 1-phenyl-2-butene can show geometrical isomerism.
Which of the following will not show geometrical isomerism?
2,3-Dimethylpent-2-ene will not show geometrical isomerism as it has two same groups (−CH3) on the same carbon atom of the double bond.
How do you find the geometrical isomerism of a compound?
When two compounds have the same molecular formula and the same structural formula but differ in the spatial arrangement of atoms or group of atoms due to the restricted rotation of double bonds (about single bond in the case of cyclic compounds), they are said to exhibit geometrical isomerism.
Which of the following compound has no geometrical isomerism?
2−methyl propene does not show geometrical isomerism.
What is the molecular geometry of the H2O molecule?
Any molecule’s molecular geometry is determined by its Lewis structure. Oxygen creates two single sigma bonds with H atoms in the H2O molecule. Then, The two lone pairs of electrons push these Hydrogen atoms on the Oxygen atom. Due to the repulsion forces of lone pairs being greater than those of bonded pairs, the arrangement of atoms is deformed.
Why does H2O2 have a tetrahedral shape?
And as per VSEPR theory, these lone pairs try to repel each other, which distorts the molecule’s shape. The molecule tries to take shape and geometry that helps in minimizing the repulsive forces between the lone pairs of electron. As a result, Hydrogen peroxide or H2O2 has a tetrahedral geometry.
How many electron groups are present in H2O molecule?
The H2O molecule possesses four electron groups. Hence it is classified as tetrahedral in terms of electron-group geometry. The two single bonds to Hydrogen and the lone pairs of Oxygen constitute the four-electron groups.
What is the hybridization of the oxygen atom in H2O?
The oxygen atom in the H2O molecule has sp3 hybridization, and the bond angle of H-O-H is 104.5° The molecular geometry and the shape of the water molecule are bent due to the repulsion forces of lone pairs.
