What do you understand by nucleophilic reagents and what type of species act as nucleophiles ? Give at least two examples.

(a) The double bond in aldehydes and ketones is reactive towards nucleophilic reagents like CN^(-) whereas that in an alkene is not. (b) Alkenes undergo electrophilic addition whereas aldehydes and ketones undergo nucleophilic addition.
