Organic Photochemistry Quiz

The primary process in organic photochemistry involves the:

• Absorption of light energy

• Formation of radicals

• Breaking of bonds

• Rearrangement of atoms

The absorption of light by an organic molecule leads to:

• The formation of a radical ion

• The excitation of an electron to a higher energy level

• The breaking of a bond

• The rearrangement of atoms

The excited state of a molecule can be:

• Singlet or triplet

• Doublet or quartet

• Quintet or sextet

• None of the above

The process of energy transfer from an excited molecule to another molecule without the emission of radiation is called:

• Fluorescence

• Phosphorescence

• Internal conversion

• Intersystem crossing

The process of a molecule returning from an excited singlet state to the ground state with the emission of light is called:

• Fluorescence

• Phosphorescence

• Internal conversion

• Intersystem crossing

The process of a molecule returning from an excited triplet state to the ground state with the emission of light is called:

• Fluorescence

• Phosphorescence

• Internal conversion

• Intersystem crossing

A photochemical reaction that involves the cleavage of a bond adjacent to the carbonyl group is called:

• Norrish Type I

• Photoreduction

• Photooxidation

• Norrish Type II

A photochemical reaction that involves the transfer of an electron from one molecule to another is called:

• Photolysis

• Photoreduction

• Photooxidation

• Photoisomerization

A photochemical reaction that involves the rearrangement of atoms within a molecule is called:

• Photolysis

• Photoreduction

• Photooxidation

• Photoisomerization

A photochemical reaction that involves the formation of a new bond between two molecules is called:

• Photolysis

• Photoreduction

• Photooxidation

• Photodimerization
