1.17 × 10¹⁵ s⁻¹ is the frequency and the wavelength is 3.43 × 10⁻⁷m of the least energetic photon that can break an average C - C bond.
WHAT IS CARBON BACKBONE ?
The carbon backbone is also called the carbon skeleton. All organic compounds are made up of carbon-carbon bonds, creating a carbon skeleton or backbone in the compounds.
Carbon Skeleton Structure :
The carbon skeleton structures consist of bending lines, periodically other elements are written in as well. The carbon skeleton characteristics that change the overall structure includes:
- Length of carbon chain (the longer it is the more zig-zags are drawn).
- Shape of the carbon chain (branches, rings, etc. all change the shape of the skeleton).
- Location of attached functional groups, they need to be put onto the correct point in the skeleton.
- Any double or triple bonds that are present, particularly as triple bonds change the shape of the skeleton.

What is wavelength?</h3>
Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.
Step 1 :
Here we have to calculate the frequency and wavelength of the least energetic photon that can break an average C - C bond and have to find out in what region of the electromagnetic spectrum is this radiation.
Bond energy of C - C = 347 kJ
It is known that E = hv
⇒ 
Where, E is the energy = 347kJ
h is the planck's constant = 
v is the frequency
Now substituting the values, frequency can be calculated as,
⇒ 
≈ 8.70 × 10¹⁴ s⁻¹ .
Formula of Wavelength :

Where, λ = wavelength
h = 6.6 × 10⁻³⁴
c = 3 × 10⁸
E = bond energy
Now substituting the values, wavelength can be calculated as,

Thus, from the above conclusion we can say that 1.17 × 10¹⁵ s⁻¹ is the frequency and the wavelength is 3.43 × 10⁻⁷ m of the least energetic photon that can break an average C - C bond.
