Nucleophiles

Postby Dianna Grigorian 1C » Fri Feb 24, 2017 3:05 pm

I understand that the nucleophile is the electron rich species that likes a positively charged nucleus. Does this mean that the nucleophiles have a net negative charge and are attracted to the positive charge on other elements?

This is very often true, but not always. For example, H2O has a net neutral charge, but because the O atom has a partial negative charge due to its large electronegativity, it can be considered a nucleophile as well. Other examples in the course reader include NH3 and NH2CH3.

Many times it depends on the formal charge of the central atom. If the formal charge is negative then the species will be a nucleophile and will be attracted to positively charged particles.
