In general terms, why do functional groups impart more chemical reactivity to families that have them? Why don't the alkanes display as many reactions as, say, the amines? Select all that apply:
Amines are Lewis bases and can be protonated.
Amines are Lewis bases and can be de-protonated.
Functional groups typically impart polarity to what would be an otherwise nonpolar hydrocarbon.
As the site of polarity, a functional group is a likely site of attack in polar or ionic reactions.
