Questions and Answers

Which type of compounds are capable of absorbing radiation in the UV and VIS?

Compounds without a chromophore group
Organic compounds without a chromophore group
Inorganic compounds
Metal complexes (correct)

What is a chromophore?

A region in a molecule where the energy difference between two molecular orbitals falls outside the range of the visible spectrum
A molecule that reflects certain wavelengths of visible light
A region in a molecule where the energy difference between two molecular orbitals falls within the range of the visible spectrum (correct)
A molecule that transmits certain wavelengths of visible light

What happens when a molecule absorbs certain wavelengths of visible light?

The molecule reflects light of the absorbed wavelengths
The molecule undergoes a change in energy associated with electron transitions (correct)
The molecule becomes colorless
The molecule emits light of the absorbed wavelengths

What is the Lambert-Beer Law?

<p>A law stating that the amount of light emerging from a sample is diminished by the amount of absorbing material in its path (A)</p> Signup and view all the answers
