Question

What are radicals? Give example of monovalent positive and trivalent negative radical.

Answer 1

Valency is the number of hydrogen

Answer 2

Radicals:

Explanation:

• A radical is an atom, molecule, or ion which has an unpaired valence electron.
• These unpaired electrons make radicals highly chemically reactive.
• Many radicals impulsively dimerize.
• These radicals have short lifetimes.

Monovalent positive radical:

• An atom, ion which can form one covalent bond is called a monovalent.
• When an electron is lost, the atoms accept a positive charge and are called positive radicals or positive ions.

e.g

• H
• Li
• Na
• K

Trivalent negative radical:

• An atom, ion which can form three covalent bonds is called a trivalent radical.
• When an electron is lost, the atoms accept a negative charge and are called negative radicals or negative ions.

e.g.

• P
• N
• As
• Sb
