क्रियात्मक समूह के साधारण नाम और सामान्य सुत्र | Class 11th Chemistry Lesson 8 | UP BOARD NCERT |

Namaskar Students! Welcome to the Mission Topper 2026 series on Chemistry Ki Duniya. In today's video, Mahendra Sir explains the concept of Functional Groups (क्रियात्मक समूह). A functional group defines the chemical properties of a compound, and knowing its General Formula is the first step in Organic Chemistry. 📚 Lecture Highlights (इस वीडियो में हम पढ़ेंगे): 🔹 1. परिभाषा (Definition): ✓क्रियात्मक समूह क्या होते हैं? (Atom or group of atoms deciding chemical properties). ✓R- समूह (Alkyl Group) का महत्व। 🔹 2. प्रमुख समूह और उनके सूत्र (Major Groups & Formulas): ✓Alcohol (अल्कोहल): R-OH (सामान्य सूत्र: C_nH_{2n+1}OH) ✓Ether (ईथर): R-O-R' (साधारण नाम: Alkyl alkyl ether) ✓Aldehyde (एल्डिहाइड): R-CHO ✓Ketone (कीटोन): R-CO-R' (अंतर कैसे पहचानें?) ✓Carboxylic Acid (कार्बोक्सिलिक अम्ल): R-COOH ✓Ester (एस्टर): R-COO-R' ✓Haloalkane (हैलोएल्केन): R-X (X = F, Cl, Br, I) 🔹 3. साधारण नाम लिखने का तरीका (Common Naming System): ✓जैसे: CH_3OH = Methyl Alcohol (मेथिल अल्कोहल) ✓CH_3-O-CH_3 = Dimethyl Ether (डाइमेथिल ईथर) This video helps you memorize the General Formulas required for solving numericals and reaction mechanisms in Class 12 Functional group general formula list, kriyatmak samuh kise kahate hain, difference between aldehyde and ketone structure, general formula of alcohol and ether, common names of organic compounds class 11, functional groups chart class 11 ncert, chemistry by mahendra sir, up board class 11 chapter 12. #FunctionalGroups #OrganicChemistry #GeneralFormula #Class11Chemistry #UPBoard2026 #MahendraSir #ChemistryKiDuniya #GOC #AlcoholPhenolEther #AldehydeKetone
