1. (A) Consider the chemical reaction below and sort out from the list the bonds that are broken and the bonds that are formed. Identify how many of each bonds are broken or formed. An example is provided for you. I Possible Bonds H-Br C-H Br-Br C-Br H H-C-H+ Br-Br H Bonds broken: One Br-Br bond is broken H H-C-Br + H-Br H Bonds formed: (B) Use the bond dissociation energies provided in the table in order to calculate the enthalpy change (AH) for the reaction given above. Express your answer in kJ. Bond H-Br C-H Br-Br C-Br Dissociation energy (D) in kJ/mol 366 410. 193 270. Hint: It will be helpful to refer to slide # 38 in Chapter 9 lecture slides to look up the equation to use here. Show work for each step. Include units and observe proper sig figs and rounding in your answer.
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.
