Definitions:

Hex-1-ene

A hydrocarbon compound with the molecular formula C6H12, characterized by the presence of a double bond between the first and second carbon atoms.

IR Absorption

The process where molecules absorb infrared light at specific frequencies, causing vibrational changes, used in spectroscopy for substance identification.

Carbonyl Stretch

Refers to the vibration of the carbon-oxygen double bond in the infrared spectroscopy region, often used to identify carbonyl-containing functional groups in organic compounds.

Characteristic Stretches

Specific vibrational movements observed in infrared spectroscopy, unique to various functional groups in a molecule.
