Predict the shape of PH3, NO3- and CCl2H2based on VSEPR theory. Show your work using Lewis dot structure. Central atom is in Bold. After drawing the Lewis structures answer the following. a) PH3 Central atom Number of bonds to the central atom Nonbonding pairs on the central atom Total bonds + nonbonding pairs Shape of the molecule b) NO3- Central atom Number of bonds to the central atom Nonbonding pairs on the central atom Total bonds + nonbonding pairs Shape of the molecule c) CCl2H2 Central atom Number of bonds to the central atom Nonbonding pairs on the central atom Total bonds + nonbonding pairs Shape of the molecule
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
