Card 2अमीन की परिभाषा

अमीन क्या होते हैं?

Answer

अमीन, अमोनिया के व्युत्पन्न हैं जो अमोनिया के एक, दो या तीनों हाइड्रोजन परमाणुओं को एल्काइल और/या एरिल समूहों द्वारा प्रतिस्थापित करके प्राप्त किए जाते हैं। सामान्य विचार: NH3 → H परमाणुओं के प्रतिस्थ…

Card 3अमीन का वर्गीकरण

अमीन का वर्गीकरण कैसे किया जाता है?

Answer

अमीन को प्राथमिक, द्वितीयक और तृतीयक के रूप में वर्गीकृत किया जाता है, यह इस बात पर निर्भर करता है कि अमोनिया के कितने हाइड्रोजन परमाणुओं को प्रतिस्थापित किया गया है। प्राथमिक: RNH2 या ArNH2 द्वितीयक…

Card 4Classification of amines

How are amines classified?

Answer

Amines are classified as primary, secondary, and tertiary depending on how many hydrogen atoms of ammonia are replaced. Primary: RNH2 or ArNH2 Secondary: R2NH or RNHR' Tertiary: R3N or R2NR' Simple …

Card 5Structure of amines

Why do amines have pyramidal geometry?

Answer

Nitrogen in amines is sp3 hybridised and has one lone pair. Three sp3 orbitals form bonds and the fourth contains the lone pair. This gives a pyramidal shape and bond angles less than 109.5°. Example…

Card 6अमीन की संरचना

अमीन में पिरामिडीय ज्यामिति क्यों होती है?

Answer

अमीन में नाइट्रोजन sp3 संकरित होता है और एक एकाकी युग्म होता है। तीन sp3 कक्षीय बंध बनाते हैं और चौथे में एकाकी युग्म होता है। इससे पिरामिडीय आकार और 109.5° से कम बंध कोण प्राप्त होते हैं। उदाहरण: ट्…

Card 7अमीन के उदाहरण

CH3NH2, C6H5NH2, CH3NHCH3 और ट्राइमेथिलमाइन को वर्गीकृत करें।

Answer

CH3NH2 = प्राथमिक एमाइन C6H5NH2 = प्राथमिक एमाइन CH3NHCH3 = द्वितीयक एमाइन ट्राइमेथिलैमाइनe = tertiary amine…

Card 8Examples of amines

Classify CH3NH2, C6H5NH2, CH3NHCH3, and trimethylamine.

Answer

CH3NH2 = primary amine C6H5NH2 = primary amine CH3NHCH3 = secondary amine Trimethylamine = tertiary amine…
