An AB2 mol- ecule must be either
linear 1bond angle = 180°2 or bent 1bond angle 180°2
. For AB3 molecules, the two most common shapes place the B atoms at the corners of an equilateral triangle. If the A atom lies in the same plane as the B atoms, the shape is called trigonal planar.
What is the molecular geometry of pbr3pbr3?
For PBr3, the central atom is Phosphorus, three bromine atoms form bonds with it, and there is one lone pair of electrons. Hence it has AX3N1 notation, and referring to the table below, we can say that it has
tetrahedral geometry
.
Is AB2 linear?
Organic compounds Organic formulas follow the convention of placing C first in the formula, fo… Q.
An AB2 molecule is described as linear
, and the A-B bond length is known. … The NH3 molecule is trigonal pyramidal, while BF3 is trigonal planar.
What is the molecular geometry of brcl4?
The answer is A) square planar. Start from the Lewis structure of the tetrafluoroborate ion, BrF−4 . The molecule will have a total of 36 valence electrons – 7 from bromine, 7 from each of the four fluorine atoms, and one extra electron to give the ion the -1 charge.
Which molecule is linear?
In
CO2
, the central C atom has 4 valence electrons. All are used up to form four bonds with O atoms. Thus, it has zero lone pair. Therefore, it is a linear molecule.

What is the Lewis Structure of OF2?
In the Lewis Structure of OF2,
both Fluorine atoms share a single bond with the Oxygen
. The central oxygen atom has two lone pairs of electrons, and the bond angle of F-O-F is 109° 27′.
Is brf4 tetrahedral?
BrF
4
–
is
square planar

What does Vsepr stand for?
The
valence shell electron pair repulsion
(VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion.
Which molecule is not linear?
Hence,
methane
is not a linear molecule.
What makes a molecule bent or linear?
The key difference between linear and bent molecules is that
linear molecules have atoms bonded to each other, forming a straight molecule
, whereas bent molecules have atoms arranged in a bend-shape with an angle. The terms linear molecules and bent molecules describe the shapes of different molecules.
Is BeCl2 a linear molecule?
BeCl2 has
a linear shape
with a bond angle of 180 degrees, where as H2O has a bent shape with a bond angle of 104.5 degrees.
