Given the stretching frequencies for the c–h bonds shown in green, arrange the corresponding bonds in order of increasing strength.

The right answer is B (2850cm-1) > A (3080cm-1) > C (3300cm-1)

It is possible to reason in terms of wavelength λ rather than frequency η (which is the inverse of the wavelength  (1 / λ)).

In the case of an electromagnetic wave propagating in a vacuum, the two quantities are linked by the relation: η = c / λ.

Planck-Einstein's relation is then written:

E = h * c /  λ

where "C" is the celerity of light in the void.

In this form, the relationship indicates that the energy of a photon is inversely proportional to its wavelength. So frequency is directly proportional to energy.

Thus, radiation with a shorter wavelength than the visible (gamma rays, X-rays, ultraviolet rays) is much more energetic than long-wave radiation (infrared rays, microwaves, radio waves). where an interaction with the material radically different.

answer; i do believe the correct answer is (river); /// good luck

- lead + phosphoric acid = hydrogen + lead(ii) phosphate
