Question

stion 6 Which of the following statements regarding nucleophilic strength is INCORRECT? The smaller the size of the atom, the more nucleophilic it is. The more electronegative an atom is, the more nucleophilic it will be. The more polarizable an atom is, the more nucleophilic it will be. Nucleophilicity increases as the density of the negative charge increases. The bulkier the nucleophile, the weaker it is.

Answer 1

Second option is incorrect.

| Electronegativity.- The more electronegative an atom is, the less nucleophilic it will be. This is because more electronegative atoms will hold electron density closer, and therefore will be less likely to let that electron density participate in a reaction. We see this in calculations and experiments that show nucleophilicity decreases as you get closer to fluorine on the periodic table (C > N>O > F)
