Question

5. THE C2-C3 bond length in
Naphthalene is...............​

Answer 1

Answer:

1.42 Å

Explanation:

As expected from an average of the three resonance contributors, the carbon-carbon bonds in naphthalene show variation in length, suggesting some localization of the double bonds. The C1–C2 bond is 1.36 Å long, whereas the C2–C3 bond length is 1.42 Å.

Answer 2

Answer:

The corect answer of this question is 1.42 Å.

Explanation:

Given - THE C2-C3 bond length

To Find - Fill in the blanks.

THE C2-C3 bond length in Naphthalene is 1.42 Å.

The carbon-carbon bonds in naphthalene show variation in length as a result of the three resonance contributors, implying that the double bonds are localised. The C1–C2 bond is 1.36 inches long, while the C2–C3 bond is 1.42 inches long.

The carbon–carbon bonds in naphthalene are not the same length as those in benzene. C1–C2, C3–C4, C5–C6, and C7–C8 have a length of around 1.36 (136 pm), but the remaining carbon–carbon bonds have a length of about 1.42 (142 pm).
