SN1 /SN2 Flashcards
SN1………..SN2
2TS………1TS
In sn1 rxn how will rate increase
Leaving group architecture ho
Carbonation ke super EDG laga ho
Sp2 hybridization carbon me attack hotahai jo ki planer Hota Hai to racemised product milta hai
In sn2 rxn how the rate of reaction increase
Better leaving group
Better nucleophile
EwG increases the rate
Antibonding orbital of leaving group me attack Hota Hai TBP geometry ban jaati hai ….leaving group jis plane me hoga uske opposite plane se attack hoga
Polar a protic solvents
Acetone, DMF ,DMSO
SN1 OR SN2 ME KINETIC PATH KOIN FOLLOW KAR RHA HAI
Sn1
Naked nucleophile I-,BR-,CL-,F-,OH-,OR-,SH-,SR-,CN-
WHICH SN MEACHANISM
Non naked like h2o, Roh does
SN2 mechanism
SN1 MEACHANISM
H2o jab as a nucleophile pr aatack karta hai to
Oxygen pr positive charge aa jata hai fir wo apna H+ loose karta hai
BRidge head carbon pr na he hum
SN1 OR SN2 KARWA SKTE HAI
Allylic and benzylic alkyl halide give which SN MEACHANISM
Both sn1 sn2
Sn2 me to ewg ki jarurat hoti hai to to haha sp2 carbon bhi present hone ke Karan ye ewg bhi hai
Bridge head carbon pr to Sn or sn2 nhi Hota
To vinylic or halobenzene ho to
Ye dono bhi sn1,sn2 dono nhi dete
F,CI,Br,l benzylic carbocation se attach hai to inka koine sa effect zada dominating hai
-l effect
Sbf5 is a
Lewis acid
0 degree carbocation kis mechanism ko follow karega
SN2
Hydrolysis Solvolysis treat like
SN1
No, of molecular orbital in CH4
