What are radicals or ions?
In chemistry, a radical is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive.
What’s the difference between radical and anion?
Radicals are very reactive species. Anions are every atom or molecule that posses negative charge.
What are free radicals mention any two examples?
Examples of Free Radicals Consider three reactive species a methyl anion, methyl cation and methyl radical. These radicals are shown below. Ethane is composed of two methyl groups connected by a covalent bond and is a very stable compound.
What are free radicals with examples?
Table 1
| Free radical | Symbol | Half-life |
|---|---|---|
| Hydrogen peroxide | H2O2 | Stable |
| Singlet oxygen | 1O2 | 10−6 s |
| Ozone | O3 | s |
| Organic peroxide | ROOH | Stable |
What is the difference between simple radical and composite radical?
Answer: a) Simple radicals: The radicals which contain only one atom are called simple radicals. b) Compound radicals: The radicals which contain more than one atom are called compound radicals.
Why free radical is neutral?
Although free radicals contain unpaired electrons, they may be electrically neutral. Because of their odd electrons, free radicals are usually highly reactive.
Is singlet oxygen a free radical?
Singlet oxygen is not a free radical but it can be formed during some free radical reactions and can trigger the formation of free radicals. Singlet oxygen can be formed by macrophages during phagocytosis and by light (in chlorophyll).
How do you identify free radicals?
A free radical can be defined as an atom or molecule containing one or more unpaired electrons in valency shell or outer orbit and is capable of independent existence. The odd number of electron(s) of a free radical makes it unstable, short lived and highly reactive.
What do free radicals do?
Free radicals are oxygen-containing molecules with an uneven number of electrons. The uneven number allows them to easily react with other molecules. Free radicals can cause large chain chemical reactions in your body because they react so easily with other molecules. These reactions are called oxidation.
