Class: Date: Name: Chapter 7 Review 26. Formal charge is: - a, the absolute value of the charge on a polyatomic anion or cation. b. the difference between the number of lone pairs of electrons and shared pairs of electrons on any atom in a Lewis structure. c. the difference between the number of valence electrons and the number of protons in any given atom. d. equal to the number of valence electrons in a free atom minus the number of shared in covalent bonds. e. the difference between the number of valence electrons in a free atom and the number of electrons assigned to the atom in a Lewis structure. 27. A Lewis structure of OCI ion is drawn below. What is the formal charge on each atom? -Ci: :0: a. Cl atom = +1 and each O atom =-1 %3D b. Cl atom = 0 and each O atom = -1 %3D c. Cl atom =-1 and each O atom %3D %3D d. Cl atom = +3 and each O atom = -2 %3! e. Cl atom = 0, one O atom 0, one O atom = = -1
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.
Chemical bond is defined as attraction between ions/molecules that results in generation of chemical compounds.
