The Simple Trick to Identify 1°, 2°, 3° Carbons in SECONDS Primary (1°), secondary (2°), and tertiary (3°) alkyl groups are classified based on the number of carbon atoms attached to the carbon bearing the functional group: primary has one carbon neighbor (e.g., CH₃-CH₂-X), secondary has two (e.g., (CH₃)₂CH-X), and tertiary has three (e.g., (CH₃)₃C-X). These classifications critically influence reactivity—primary alkyl groups favor SN2 reactions due to low steric hindrance, while tertiary groups favor SN1/E1 reactions due to stable carbocation formation via hyperconjugation. Secondary groups exhibit intermediate behavior. In oxidation, primary alcohols form aldehydes/carboxylic acids, secondary alcohols yield ketones, and tertiary alcohols resist oxidation. Understanding these differences is essential for predicting reaction pathways in organic synthesis and biochemistry. #iupacnomenclatureoforganicchemistry #shorts #education #gpat #bpharmacy #neet #niperexam #entranceexam #organic #carbon #alkyl For other chemistry & biology related videos, click below, / @shashanktewari
