What kind of bond forms between the two carbon atoms in C₂H₄?

• single

• double

• triple

• quadruple

In a covalent bond, the electrons are shared between two atoms. But sometimes the electrons are pulled closer to one atom than the other, resulting in an unequal sharing of electrons. Why does this happen?

• one atom is more electronegative than the other

• one atom has a higher ionization energy than the other

• one of the atoms has more valence electrons than the other

• one of the atoms can form more bonds than the other

Which of the following would have the weakest bond energy? You will need to look at the Lewis structures to determine this.

• HF

• SO

• N₂

• O₂
