Aldehydes are more reactive than  ketones due to steric and electronic factors 
Alcohols act as lewis bases due to presence of lone pair of electrons on O-atom 
Amines are more basic than amides and alcohols 
Amines and phenols are more reactive than benzene due to the presence of highly activating 
groups( -OH,-NH 2) 
Amines are less acidic thanalcohols due to more electronegative O-atom 
Primary amines have higher boiling point than tertiary amines due to more H-bonding 
Aliphatic amines are stronger bases than aromatic amines due to –I effect of alkyl gps

-NH2 GP is protected before nitration by acetylation 
 
the lone pair of electrons on nitrogen is less available fordonation to benzene ring by  
resonance. Therefore, activatingeffect of –NHCOCH 3 group is less than that of amino group.

FAQs on Conversions -Chapter Notes , Organic Chemistry, Class, CBSE - Class 12

1. What is a conversion in organic chemistry?
Ans. Conversion in organic chemistry refers to the process of converting one functional group into another. This is typically achieved by using a series of chemical reactions to modify the molecular structure of a compound, resulting in the formation of a new functional group.
2. Why are conversions important in organic chemistry?
Ans. Conversions are important in organic chemistry because they allow chemists to modify the properties of a compound by changing its functional group. This can have a significant impact on the compound's reactivity, solubility, and other chemical properties, making it a valuable tool for drug design, material science, and other applications.
3. What are some common types of conversions in organic chemistry?
Ans. There are many different types of conversions in organic chemistry, including: - Reduction: The conversion of a carbonyl group (such as a ketone or aldehyde) to an alcohol - Oxidation: The conversion of an alcohol to a carbonyl group - Halogenation: The addition of a halogen atom (such as chlorine or bromine) to a compound - Nitration: The addition of a nitro group (NO2) to a compound - Esterification: The conversion of a carboxylic acid to an ester
4. How are conversions typically carried out in the laboratory?
Ans. Conversions in organic chemistry are typically carried out using a combination of chemical reagents and solvents. The specific reactions used will depend on the desired functional group conversion, as well as the starting material. In some cases, specialized equipment or techniques may be required to carry out the reaction, such as refluxing or distillation.
5. What are some common challenges associated with organic conversions?
Ans. Organic conversions can be challenging due to the complexity of the reactions involved, as well as the need for precise control over reaction conditions (such as temperature, pH, and concentration). Additionally, some functional groups are more difficult to convert than others, and may require specialized reagents or reaction conditions. As a result, organic conversions often require a significant amount of trial and error to optimize the reaction conditions and achieve the desired product.
