## What is radical reaction in chemistry?

A radical substitution reaction is a reaction which occurs by a free radical mechanism and results in the substitution of one or more of the atoms or groups present in the substrate by different atoms or groups. The initiation step in a radical chain reaction is the step in which a free radical is first produced.

## What are basic radicals?

Basic radicals Positively charged radicals are called a basic radical. Acid radicals are formed by removal of hydrogen ion (H+). Basic radicals are formed by the removal of hydroxide ion (OH–). Example: H2S04 loses one H+ ion to form HSO4– ion.

## Are ions radicals?

A radical ion is a free radical species that carries a charge. Radical ions are encountered in organic chemistry as reactive intermediates and in mass spectrometry as gas phase ions. Positive radical ions are called radical cations whereas negative radical ions are called radical anions.

## What is the only positive radical?

Radicals are the Positive and the Negative ions which have at least one unpaired electrons. Positive Radicals are —→ 1). Sodium = Na⁺

## Is a positive radical?

A radical is an atom of an element or a group of atoms of different elements that behave as a single unit with a positive or negative charge on it. Positively charged radicals are called basic radicals such as Na+, NH4+ etc. Basic radicals are also known as cations and acid radicals are known as anions.

## What is negative radical?

The square root of a negative number does not exist among the set of Real Numbers. The imaginary number first appeared in print in the year 1545. The imaginary number “i” is the square root of negative one. An imaginary number possesses the unique property that when squared, the result is negative.

## Is negative square root of 64 a real number?

If you enter SQRT(-64) into a spreadsheet on your computer, you will get an error message saying something like “argument must be greater or equal to 0” because the square root of negative 64 is not possible. There is no real number multiplied by itself that will equal -64.
