Examples Ethene C2H4 Propene C3H6 Butene C4H8 Reactions Alkenes are more reactive than alkanes due to the electronrich double bond They undergo addition reactions where atoms or groups are added across the double bond Examples include hydrogenation halogenation and hydration 3 3 Alkynes Unsaturated hydrocarbons containing at least one carboncarbon triple bond CC General formula CnH2n2 Examples Ethyne C2H2 Propyne C3H4 Butyne C4H6 Reactions Alkynes similar to alkenes undergo addition reactions However they can react twice due to the presence of two pi bonds Examples include hydrogenation halogenation and hydration 4 Alcohols Contain a hydroxyl group OH attached to a saturated carbon atom General formula ROH Examples Methanol CH3OH Ethanol C2H5OH Propanol C3H7OH Reactions Alcohols can undergo various reactions including dehydration to form alkenes oxidation to form aldehydes or ketones and esterification with carboxylic acids 5 Aldehydes Contain a carbonyl group CO where the carbonyl carbon is attached to at least one hydrogen atom General formula RCHO Examples Formaldehyde HCHO Acetaldehyde CH3CHO Propanal C3H7CHO Reactions Aldehydes undergo nucleophilic addition reactions at the carbonyl carbon forming alcohols hemiacetals and acetals They can also be oxidized to carboxylic acids 6 Ketones Contain a carbonyl group CO where the carbonyl carbon is attached to two carbon atoms General formula RCOR Examples Acetone CH3COCH3 Propanone C3H6O Butanone C4H8O Reactions Ketones undergo similar reactions to aldehydes such as nucleophilic addition and

Trimethylamine CH33N Reactions Amines are basic compounds that react with acids to form salts They can also undergo reactions such as alkylation acylation and amide formation 9 Ethers Contain an oxygen atom bonded to two carbon atoms General formula ROR Examples Dimethyl ether CH3OCH3 Diethyl ether C2H5OC2H5 Reactions Ethers are generally unreactive but they can be cleaved by strong acids or oxidizing agents 10 Esters Contain a carbonyl group CO bonded to an alkoxy group OR General formula RCOOR Examples Methyl acetate CH3COOCH3 Ethyl acetate CH3COOC2H5 Reactions Esters undergo hydrolysis in the presence of acids or bases to form carboxylic acids and alcohols They can also be reduced to alcohols Understanding Reaction Mechanisms A fundamental aspect of organic chemistry lies in understanding the reaction mechanisms that govern the transformation of molecules These mechanisms provide a detailed stepby step description of how bonds break and form during a reaction Nucleophilic Attack A nucleophile a species with an electronrich atom attacks an electrophilic center electrondeficient leading to the formation of a new bond Electrophilic Attack An electrophile a species with an electrondeficient atom attacks a nucleophilic center leading to the formation of a new bond Addition Reactions Atoms or groups are added across a multiple bond typically a double or triple bond Elimination Reactions A small molecule such as water or HCl is removed from a molecule leading to the formation of a double or triple bond Substitution Reactions One atom or group is replaced by another atom or group 5 Spectroscopy and Analysis Several spectroscopic techniques play a vital role in identifying and characterizing organic compounds These techniques provide crucial information about the structure bonding and functional groups present within a molecule Nuclear Magnetic Resonance NMR Spectroscopy Provides information about the carbon and hydrogen atoms within a molecule Infrared IR Spectroscopy Identifies the functional groups present in a molecule based on their characteristic vibrational frequencies Mass Spectrometry MS Determines the molecular weight of a compound and provides information about its fragmentation pattern Conclusion Functional groups are the building blocks of organic chemistry Understanding their properties reactions and the underlying mechanisms that govern their behavior is crucial for anyone interested in organic chemistry By mastering these concepts youll gain a deeper appreciation for the complexity and beauty of organic
