Question

An alkyl halide on reaction with nucleophile undergoes inversion on configuration.out of sn1 and sn2 which mechanism folloowed

Answer 1

Also as Electronegativity increases, nucleophilicity decreases because More the Electronegativity — More tightly it is held — Less ability to donate it's pair of electrons. Steric Effect: The bulkier a given nucleophile is, the slower the rate of its reactions [and therefore the lower its nucleophilicity].
