Negative radicals
Brivalent basic radicals
Composite acidic radicals
Answers
Answer:
1. A group of atoms possessing either positive or negative charge by losing or gaining one or more electrons is called a radical . ... All other radicals are negatively charged. SO-23,SO-24,CO-23 are some examples of bivalent negative radicals.
2. A trivalence basic radical is defined as a cation having three valencies. Examples of trivalent basic radicals are Al3+ (Aluminium cation), Au + 3 (Auric ion), Bi3+ (Bismuth cation), Cr3+ (Chromiun (III) ion), and Fe3+ (Ferric ion).
3. Composite radicals are groups of atoms of different elements, which may carry either positive charge or negative charge ,which behave exactly like a single atom. Examples: methane, methyl, acetyl. Benzene, phenyl, or cyclohexane, acetylimino, cyclohexanecarbonyl etc.
