A) Chemically reactive
B) Chemically inactive
C) Anions
D) Cations
Correct Answer: A
Solution :
[a] Chemically reactive A free radical may be defined as atom or a group of atoms having unpaired electron. These are produced by hemolytic cleavage of a covalent bond. For example \[\begin{align} & Cl-Cl\text{ }\xrightarrow{hv\,or\,\Delta }\text{ }Cl+Cl \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,chlorine\text{ }free\text{ }reactions \\ \end{align}\] There are highly reactive chemical species because of their strong tendency of carbon atom carrying odd electron to acquire one more electron to complete its octet.
