In the context of organic chemistry, how are relative and absolute dating methods used to determine the age of organic compounds?
A
Both relative and absolute dating rely solely on the chemical composition of the compounds.
B
Relative dating uses the position of compounds in sediment layers, while absolute dating uses radiometric techniques.
C
Relative dating uses radiometric techniques, while absolute dating uses the position of compounds in sediment layers.
D
Relative dating uses carbon dating, while absolute dating uses the position of compounds in sediment layers.
Verified step by step guidance1
Understand the concept of relative dating: In organic chemistry, relative dating involves determining the age of a compound based on its position within sedimentary layers. This method does not provide an exact age but rather an estimate based on the compound's stratigraphic context.
Understand the concept of absolute dating: Absolute dating provides a more precise age of a compound by using radiometric techniques. This involves measuring the decay of radioactive isotopes within the compound to calculate its age.
Differentiate between the two methods: Relative dating is based on the stratigraphic position of compounds, while absolute dating relies on radiometric techniques to determine a specific age.
Consider the role of carbon dating: Carbon dating is a form of radiometric dating specifically used for organic compounds. It measures the decay of carbon-14 to estimate the age of organic materials.
Apply the concepts to the problem: Recognize that the correct understanding is that relative dating uses the position of compounds in sediment layers, while absolute dating uses radiometric techniques, such as carbon dating, to determine the age of organic compounds.
