WebDec 13, 2009 · The answers given for the question is correct and the concept given is wrong.consider protic solvent it consists of H+ ions since bonds between similar sized atoms is strong,the bond between smaller atoms will be stronger if F- is in polar protic solvent,it forms HF molecule which will be more stable than other halogen hydrides

WebOct 9, 2024 · The rate of SN2 reaction is maximum when the solvent is polar aprotic such as DMSO (dimethyl sulphoxide) (CH3)2S→O. In such solvents, the nucleophile is not solvated and can freely attack the substrate. Also, the polar nature of the solvent helps in the cleavage of C−X bond where X is the leaving group. WebHard nucleophiles are small, have high charge densities, and are weakly polarizable. Examples are ROH, RO⁻, RNH₂, NH₂⁻, and F⁻ Their orbitals do not necessarily overlap very well with the electrophile's accepting orbital, but the electrostatic attraction directs them and aids the …
