WebbIn general, a negatively charged compound is going to be a stronger nucleophile than a neutral compound. In addition, as one proceeds down a given column of the periodic table, the nucleophilicity increases because the electrons are not held as tightly to the nucleus (electronegativity decreases). WebbBecause nucleophiles donate electrons, they are by definition Lewis bases. The relative strengths of nucleophiles can be correlated with: A negatively charged nucleophile is always more reactive than its conjugate acid. Thus HOX is a better nucleophile than HX2O and ROX is better than R OH. OH −>CH 3COO −>OCH 3−>C 6H 5O −

WebbThe strength of electrophile is given by its electrophilicity, which is the ability to attract electrons. Therefore, a positively charged species that requires electrons to obtain stability is a good and strong electrophile. WebbThe order of nucleophilicity can be given as follows: Br - < F - < OH - c. OH - will be a stronger nucleophile than H 2 O as negatively charged species are stronger nucleophiles … jelena gagarina

For instance, carbocations (concerted transition state, or intermediate), α carbons of carbonyls, or atoms with lots of electron withdrawing groups nearby are great electrophiles.
