Which of the following statements about bonds between two carbon atoms is/are correct? (I) Bond strength increases as more electrons are shared between the atoms.
(II) Bond strength increases as the overlap between atomic orbitals increases.
(III) Hybrid orbitals are used to describe (account for) the geometry (bond angles) around each carbon atom.
A)I
B)II
C)III
D)Only two of these are correct statements.
E)All three are correct statements.

Question

Quizplus · Accepted Answer

All three statements are correct regarding bonds between two carbon atoms. (I) Bond strength does indeed increase as more electrons are shared between the atoms, which is why triple bonds are stronger than double bonds, which are in turn stronger than single bonds. (II) Bond strength also increases with greater overlap between atomic orbitals, as this allows for a more effective sharing of electrons. (III) Hybrid orbitals are indeed used to describe the geometry around each carbon atom, explaining the bond angles observed in molecules.
