Due to small size of N atom, its valence electron are close enough to form pi bond with other N atom. Due to large size of P atom its outer electron are farther and separated and hence unable to form triple bond.so phosphorus bonds to other 3atom to complete their octat.

Sn1 reaction occur in two steps .first is the formation of carbocation then attack by nucleophile to give the desired product.sn1 reaction also known as solvolysis because here solvent act as a nucleophile .it is favoured by polar protic solvent like water alcohol.f ollow first order kinetics.rate of reaction depend only on the concentration of alkyl halide .rate of sn 1 reaction is directly proportional to stability of carbocatio.sn 1 reaction is not possible for three membered ring because carbocation is sp2 hybridized which is planar and in three membered ring angle is 60 it become higly unstable does not favour sn1 reaction.in bridgeded compound also does not favour sn1 reaction due to non planarity .rate of sn1 reaction directly proportional to good leaving grouo .good leaving group means weak conjugate base .for sn1 reaction weak nucleophile is required .

Sia ? 4 years, 6 months ago

An agonist is a drug that binds to the receptor, producing a similar response to the intended chemical and receptor. Whereas an antagonist is a drug that binds to the receptor either on the primary site, or on another site, which all together stops the receptor from producing a response.
