Why tertiary alkyl radical more stable than primary?
Tertiary alkyl radicals are more stable than primary alkyl radicals because they have more hyperconjugation interactions with adjacent carbon-hydrogen bonds that can delocalize the radical's charge, stabilizing it. In addition, tertiary alkyl radicals are surrounded by more alkyl groups, which provide steric hindrance and shield the radical from reacting with other molecules.
What is state of hybridisation of c in carbon free radical?
In a carbon free radical, the carbon atom has three unpaired electrons in its outer shell, indicating sp2 hybridization. This allows the carbon atom to form three covalent bonds with other atoms.
How does an alkyl group differ from its parent alkane?
An alkyl group is a portion of an alkane molecule that has a hydrogen atom removed. This removal of a hydrogen atom leads to the formation of a free radical, giving the alkyl group its characteristic reactivity. Alkyl groups are used as building blocks in organic chemistry and can be attached to other functional groups to create a wide variety of organic compounds.
What are the 3 steps in the free radical substitution?
The three steps in free radical substitution are initiation, propagation, and termination. In initiation, a free radical is generated. In propagation, the free radical reacts with a molecule to form a new free radical. In termination, two free radicals react with each other to form a stable product, ending the chain reaction.
What is the role of sodium in wurtz reaction?
One electron from the metal is transferred to the halogen to produce a metal halide and an alkyl radical.R-X + M → R• + M+X− The alkyl radical then accepts an electron from another metal atom to form an alkyl anion and the metal becomes cationic. This intermediate has been isolated in a several cases.R• + M → R−M+ The nucleophilic carbon of the alkyl anion then displaces the halide in an SN2 reaction, forming a new carbon-carbon covalent bond.R−M+ + R-X → R-R + M+X−

What is an aralkyl?
An aralkyl is a univalent radical derived from an alkyl radical by replacing one or more hydrogen atoms by aryl groups.

In a carbon free radical, the carbon atom has three unpaired electrons in its outer shell, indicating sp2 hybridization. This allows the carbon atom to form three covalent bonds with other atoms.
What is an alkylamino?
An alkylamino is a group or radical which contains both an alkyl and an amino group.

Why tertiary alkyl halides do not undergo wurtz reaction?
Tertiary alkyl halides do not undergo the Wurtz reaction because they do not have any active hydrogen atoms that can participate in the radical coupling step. Without an active hydrogen, the radical mechanism required for the Wurtz reaction cannot proceed.
What is an alkoxy?
An alkoxy is any univalent radical R-O- or anion R-O-, where R is an alkyl group.
When was Free Radical Research created?
Free Radical Research was created in 1985.
When was Free Radical Centre created?
Free Radical Centre was created in 2005.
