Question

the question doesnt ask for ranking but can you expalin how ranking works and the rules for ranking ?

-) Rank the following from greatest (1) to least (3) for the terms given. No written explanation is required. a) nucleophilicity in methanol b) acidity in THF c) rate of reaction with sodium iodide in acetone. d) rate of solvolysis in methanol e) basicity in H2O :

Answer 1

a Lor use we * Nucleophilicity depends on Electronegativity, Siße (polarizability) and solvent. * Nucleophile shares its elections as electronegativity increases their ability to share elections decreases. Here electronegativity order is É >ous 1. So, fluoride if weakest nucleophile also it is very small size so polar Solvents like meon completely shield its electone, further making it a Weak nucleophile, oxygen is more effectively solvated than s because between O ands sulpur is larger size hence its election density is more diffused (polarized) making it hard to be solvated by protinc Meot solvent, this thing make s strongest wacheophite- So, now the order is viv> vous nei

- acid b. Acidity mainly depends on the Stability of conjugate and. - HA A THO acid conjugate & most acidic because the conjugate base formed is highly stable. To *Here anon is highly delocalized all the way through the benzene ring making it very 1. Stasie species. Resonance Henti Here, Stabili 3 ed Benzylic anion species Next, H is mo =h is most stable because -CECat has high s character making it is more electronegative e than their c=6H & -¢-GH counterparts. than their ī ī" i i hence the anionic form of this species is stabilized. CAK? 0 + 14® Anion Stabilized by triple bonded carbons. U KA, no stabilization of coniugate and of this species existe hence it is least stable. order: H > > then,

for alkylhalides primarily depends on 6 Rate of reaction with Nag the steric factore- - reactive because of less steric hinderance hare, primary alkylhalides are more Br = X A Br so Brzo is hoofreact most reactive It or and Between , t imbr Ě KHH reactive because it has less steric hindrance Br is more HA En on compared to А ну for qe attack Fodide anion attack ię difficult order. Boo x ... By > Br

In the given time this is all I could answer. Good luck.
