(a)

Interpretation Introduction

Interpretation: The ππ* Transition needs to be defined.

Concept Introduction: When transition of electrons happens, there is a certain amount of change in energy levels, associated with it, and this provides more information about the molecular structure and its properties.

(b)

Interpretation Introduction

Interpretation: The I0 needs to be defined.

Concept Introduction: The magnitude of photoelectric current increases when there is an increase in the intensity of incident radiation.

(c)

Interpretation Introduction

Interpretation: The Conjugated π - System needs to be defined.

Concept Introduction: A conjugated system generally decreases the energy level of a molecule, thus increasing its stability.

(d)

Interpretation Introduction

Interpretation: The Chromophore needs to be defined.

Concept Introduction: Chromophore is a group of chemicals, that provides color for a molecule by way of absorption of light at a particular frequency.

(e)

Interpretation Introduction

Interpretation: The Visible Spectrum needs to be defined.

Concept Introduction: The visible spectrum helps in the study of the universe and earth.

(f)

Interpretation Introduction

Interpretation: The Cut-Off point of a solvent needs to be defined.

Concept Introduction: All light is absorbed by the solvent, below the cut-off point of the solvent.

(g)

Interpretation Introduction

Interpretation: The Electronic transition needs to be defined.

Concept Introduction: When the energy of an electron gets transferred from one energy level to another energy level, then it is called electronic transition.

(h)

Interpretation Introduction

Interpretation: The absorbance needs to be defined.

Concept Introduction: The light absorbing capacity of a substance is called absorbance. The incident light has a specified wave length.

Which is TRUE for spectroscopy of a mixture?   A. The absorbance for a mixture at a particular wavelength is the sum of the absorbances for the components that absorb at the particular wavelength.   B. Spectrophotometers can differentiate between mixture components that absorb at the same wavelength.   C. Each component in a mixture has the same molar absorptivity at the same wavelength.   D. The concentration for each component in a mixture is easily calculated by least squares for guesses of each component when the individual spectra are well resolved.
