Explanation Refer to figure 7.7. The bonding atomic radius of P ( r P ) is 1.07 A o The bonding atomic radius of Br ( r Br ) is 1.20 A o . The P − Br distance is calculated by the formula. r P − Br = r P + r Br Substitute the values of r P and r Br in the above formula. r P − Br = 1.07 A o + 1.20 A o = 2.27 A o The bonding atomic radius of As ( r As ) is 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 b…

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…
