The least stable free radical is
Updated On: Jun 23, 2023
- $ C{{H}_{3}}CHCH{{(C{{H}_{3}})}_{2}} $
- $ C{{H}_{2}}C{{H}_{2}}CH{{(C{{H}_{3}})}_{2}} $
- $ C{{H}_{3}} $
- $ C{{H}_{3}}C{{H}_{2}}C{{(C{{H}_{3}})}_{2}} $
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
As the number of alkyl groups attached to the carbon containing odd electron increases, number of hyperconjugative structures increases, and thus, the stability increases. $CH _{3}$ due to lack of alkyl group, attached to the ${ }^{\circ} C$, is least stable.

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.

Importance of Organic Chemistry:
Organic chemistry is applicable in a variety of areas including-
- Medicines: Example- Aspirin which is a headache medicine and Ibuprofen is a painkiller, both are organic compounds. Other examples include paracetamol.
- Food: Example- Starch which is a carbohydrate is an organic compound and a constituent of rice and other grains. It is the source of energy.
- Clothing: Example- Nylon, Polyester and Cotton are forms of organic compounds.
- Fuels: Examples- Gasoline, Petrol and Diesel are organic compounds used in the automobile industry at large.
