Why does iodine have the longest bond length?
I2 has the largest bond length due to the following reasons: The size of iodine is largest. Due to large size of I, the internuclear distance between the two atoms increases. As the internuclear distance increases, the bond length also increases.
What causes longer bond lengths?
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.15 thg 8, 2020

What is the bond length of iodine?
Even stronger effects of intermolecular interactions were observed in iodine. The bond length, d, in gaseous 12 is 2.666/~ [2], while in crystalline 12 it is 2.715/~ [3].
Which bond has the longest bond length?
Carbon-carbon bond (C-C)
What is the bond energy of iodine?
The bond energy in the gaseous diatomic species II is 151.088 kJ mol-1.
What determines bond strength?
The strength of a bond between two atoms increases as the number of electron pairs in the bond increases. Thus, we find that triple bonds are stronger and shorter than double bonds between the same two atoms; likewise, double bonds are stronger and shorter than single bonds between the same two atoms.

Which of the following has the largest bond order?
Nitrogen has highest bond order.
How does bond length depend on electronegativity?
As the strength of a particular bond depends on its bond length, it follows that the shorter the bond, the greater the electronegativity of the cation, the greater the build-up of electron density along the bond and the greater the enhancement of electron density toward the bond path.
What are the properties of iodine?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. Above 700 °C (1,300 °F), dissociation into iodine atoms becomes appreciable.
Which halogen will have the longest bond length?
Solution : Longest bond length is HI, due to large atomic size of `I_(2)` highest bond energy is HF, due to unlike poles more attraction small bond length.
Which molecule has the longest no bond length?
Out of NO+, NO2-, NO3- which has the longest NO bond and which has the shortest NO bond? The bond order for NO+ is 3 electrons/1 bonding group = 3. The bond order for NO?2 is 3 electrons/2 bonding groups = 3/2 = 1.5. The bond order for NO?3 is 4 electrons/3 bonding groups = 4/3 ? 1.33.
Which of the following has highest bond energy?
The S?S bond has highest energy and highest bond strength For example, the bond energies of S?S and O?O bond are 49 and 33 kcal/mol respectively.
Which has maximum bond energy?
Fluorine has high electronegativity. Because of its small size and short bond, the are repulsions between electrons and weakens the bond. Chlorine is next to Fluorine in electronegativity and it has sufficient bond length and size. So, it has maximum bond energy.
Which bond is the strongest?
In chemistry, covalent bond is the strongest bond. In such bonding, each of two atoms shares electrons that binds them together. For example, water molecules are bonded together where both hydrogen atoms and oxygen atoms share electrons to form a covalent bond.
What is the strongest chemical bond and why?
Covalent bonds are the strongest (*see note below) and most common form of chemical bond in living organisms. The hydrogen and oxygen atoms that combine to form water molecules are bound together by strong covalent bonds. The electron from the hydrogen atom shares its time between the hydrogen atom and the oxygen atom.
What element has the strongest bond?
The strongest bonds found in chemistry involve protonated species of hydrogen cyanide, carbon monoxide, and dinitrogen.
