Question

four substances are tested for different properties. the results of the tests are in the table below. substance combustible reactivity solubility in water solubility in ether boiling point (°c) w yes yes soluble insoluble 883 x yes no insoluble insoluble 2,750 y yes no insoluble soluble 196 z no yes soluble soluble 98 which substance is most likely an alkane? o w o x o y o z

Explanation:

Step1: Recall alkane properties

Alkanes are combustible, non - reactive (inert under normal conditions), insoluble in water and soluble in non - polar solvents like ether.

Step2: Analyze each substance

Substance W: Combustible, reactive, not consistent as alkanes are non - reactive.
Substance X: Combustible, non - reactive, soluble in water (alkanes are insoluble in water), not consistent.
Substance Y: Combustible, non - reactive, insoluble in water, insoluble in ether (alkanes are soluble in ether), not consistent.
Substance Z: Combustible, non - reactive, insoluble in water, soluble in ether, consistent with alkane properties.

Answer:

Z
