Following is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.)

is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs unshared pair(s) of electrons has a linear shape. A is a description of the three-dimensional arrangement of atoms Complete the concepts below by supplying the appropriate term. within a molecule. The the geometry of individual molecules from the number of electron pe surrounding their central atoms. A molecule consisting of only two atoms has atoms bonded to the central shape. A molecule with atom with molecule with atoms bonded to the central atom with unshared pair(s) of electrons has a trigonal planar shape. The measure of the degree of inequality in the attraction of bonding electrons to various locations within a molecule is called there is an equal sharing of electrons between the two atoms. While a molecule may be A molecule may be when when it has a net dipole as a result of the opposing charges.
Which statement A-D about VSEPR theory is not correct? Select one: a. The molecular shape or geometry can differ from the electron-pair geometry. b. In VSEPR theory, the shape or geometry of a molecule is determined by electron-electron repulsion. c. The steric number of a central atom is the sum of the number of bonded atoms and lone pairs around the central atom. d. The steric number has five values from 2 to 6. e. Statements A-D are all correct. Clear my choice
