Correct order of bond length in two organic molecules

In summary, the conversation discusses the correct relation between x and y, with options A, B, C, and D provided. It is determined that option C (x<y) is correct because x takes part in resonance, increasing its stability. The conversation also mentions the Hückel rules, specifically the 4n + 2 Π electron rule, and how it applies in this situation. It is noted that more resonance results in a longer bond, but it is not clear what it is being compared to.

Homework Statement

: [/B]The correct relation is:
A. x=y
B. x>y
C. x<y
D. None.
Please refer to picture attached.

Homework Equations

: [/B]As stability increases, bond length decreases. When a Π bond is delocalised i.e it takes part in resonance, stability increases.

The Attempt at a Solution


I think x takes part in resonance.
Hence x is more stable than y.
Thus x<y i.e C is correct option.

Compared to what?
 

1. What is the definition of bond length?

Bond length is the distance between the nuclei of two bonded atoms in a molecule.

2. How do bond lengths affect the properties of organic molecules?

The bond lengths in organic molecules can affect their shape, stability, and reactivity. Longer bond lengths can result in more flexible molecules, while shorter bond lengths can make a molecule more rigid. Bond lengths also play a role in determining the polarity of a molecule, which can affect its solubility and interactions with other molecules.

3. How can the correct order of bond length in two organic molecules be determined?

The correct order of bond length in two organic molecules can be determined through experimental methods such as X-ray crystallography or spectroscopy. These techniques can provide precise measurements of bond lengths in a molecule, allowing for comparisons between different molecules.

4. What factors can influence the bond lengths in organic molecules?

The bond lengths in organic molecules can be influenced by a variety of factors, including the types of atoms involved in the bond, the hybridization of the atoms, and the presence of neighboring atoms or functional groups. The electronic structure and bonding patterns of a molecule can also play a role in determining bond lengths.

5. What is the significance of understanding the correct order of bond length in organic molecules?

Understanding the correct order of bond length in organic molecules can provide insight into the structure and properties of these molecules. It can also aid in predicting the reactivity and behavior of a molecule. Additionally, knowledge of bond lengths can assist in the design and synthesis of new organic compounds for various applications in fields such as medicine, materials science, and agriculture.
