Why aniline is less basic than cyclohexylamine? |
|
Answer» heya....4.20am #.....In cyclohexylamine, the electron donating group is attached to SP3 hybridized cyclohexane RING while in case of aniline it is attached with sp2 hybridized carbon containing benzene ring. Due, to more s -character in benzene ring, here BECOMES the de localization of π-electrons in the ring and further the NH2 -group donates more electron to the ring so that it reduces the +ve charge centers and stabilizes the ring and makes it less acidic means the basicity increases. While , in case of cyclohexylamine, the lone pair of electron donating NH2 -group is not de- localized over cyclohexane ring and is available for DONATION, which makes the compound more BASIC than aniline.......# tysm..................#kundan |
