2.

Why do heteroatoms confer reactivity on a particular molecule?

A)

Because they have lone pairs and create electron-rich sites on carbon.

B)

Because they have lone pairs and create electron-deficient sites on carbon.

C)

Because they are electronegative and act as electrophiles.

D)

Because they are electropositive and act as nucleophiles.

3.

Why do p bonds confer reactivity on a particular molecule?

A)

Because p bonds are difficult to break in chemical reactions.
