Which of the following lists contains common heteroatoms found in organic molecules?

• N, O, S, P, Cl

• Na, O, S, P, Cl

• Na, Mg, S, N, Cl

• Na, Mg, O, N, Cl

Why do heteroatoms confer reactivity on a particular molecule?

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

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

• Because they are electronegative and act as electrophiles.

• Because they are electropositive and act as nucleophiles.

Why do pi bonds confer reactivity on a particular molecule?

• Because pi bonds are difficult to break in chemical reactions.

• Because pi bonds make a molecule an acid.

• Because pi bonds are easily broken in chemical reactions.

• Because pi bonds make a molecule an electrophile.
