In the replacement reaction `rarrC-I+MF rarr rarr C-F+MI` The reaction will be most favourable if `M` happens to beA. NaB. KC. RbD. Li. |
|
Answer» Correct Answer - C `3^(@)` Alkyl halides undergo `S_(N^(1))` reaction in which a nucleophiles attacks a carbocation. Thus more the ionic character of the M-F bond, more favourable will be the replacement reaction. Since amongest Li, Na, K and Rb, Rb has the largest size, therefore Rb-F bond has the highest ionic character and therefore, option (C ) is correct. |
