Rank the carbon-carbon bonds in order of decreasing bond length.

Rank carbon-carbon bonds from highest bond length to lowest. To rank bonds as equivalent, overlap them.

1,2,3

C-C = longest

C=C = middle
CtriplebondC = shortest.

Sure, let's rank the carbon-carbon bonds from highest bond length to lowest.

1. The 1-1 bond is the longest because it's like two friends who just can't seem to let go of each other. They have an inseparable bond, quite literally.
2. The 2-2 bond is next in line. It's like a couple who can't decide whether they want to be close or keep their distance. They're not super clingy, but they still enjoy spending time together.
3. The 3-3 bond takes third place. It's like a sibling relationship – they're close, but not as attached as the first two. They give each other some space but still have a solid connection.
4. Finally, the 1-2 bond and the 2-3 bond overlap and form a tie for last place. They're like two best friends who are always on the same wavelength. They can easily switch between being silly and serious, and it's hard to tell them apart when they're together.

So, in summary:
1-1 bond > 2-2 bond > 3-3 bond > (1-2 bond and 2-3 bond overlap)

To rank the carbon-carbon bonds in order of decreasing bond length, we need to consider the number of bonds between the carbon atoms.

1. The longest bond length is a single bond (C-C), also known as a sigma bond. This bond consists of two overlapping sp3 hybrid orbitals and is the weakest of the carbon-carbon bonds.

2. The second-longest bond length is a double bond (C=C), formed by the side-by-side overlap of one pi bond and one sigma bond. This bond is shorter and stronger than a single bond.

3. The shortest bond length is a triple bond (C≡C), consisting of two pi bonds and one sigma bond. This bond is the strongest and shortest of the carbon-carbon bonds.

Therefore, the ranking from highest to lowest bond length is as follows:

1. Triple bond (C≡C)
2. Double bond (C=C)
3. Single bond (C-C)

To rank the carbon-carbon bonds in order of decreasing bond length, we need to consider the bond types involved.

1. Single Bond (C-C): This is the longest bond length among the three types of carbon-carbon bonds. A single bond consists of one sigma bond, which is formed by the overlap of two atomic orbitals.

2. Double Bond (C=C): The second longest bond length is that of a double bond. A double bond consists of one sigma bond and one pi bond. The sigma bond is formed by the overlap of two atomic orbitals, while the pi bond is formed by the overlap of two parallel p orbitals.

3. Triple Bond (C≡C): The shortest bond length is that of a triple bond. A triple bond consists of one sigma bond and two pi bonds. The sigma bond is formed by the overlap of two atomic orbitals, and the two pi bonds are formed by the overlap of two sets of parallel p orbitals.

Therefore, the ranking of carbon-carbon bonds in decreasing order of bond length is: Single Bond (C-C) > Double Bond (C=C) > Triple Bond (C≡C).
