Question

question 3 · 1 point
which of the following alcohols is a liquid at room temperature?
select the correct answer below:
ethanol
butanol
methanol
all of the above

Explanation:

Step1: Recall physical states of alcohols

Methanol (\(CH_3OH\)), ethanol (\(C_2H_5OH\)), and butanol (\(C_4H_9OH\)) have relatively low - molecular weights.

Step2: Consider room - temperature range

Room temperature is approximately \(20 - 25^{\circ}C\).

Step3: Analyze boiling points

The boiling point of methanol is \(64.7^{\circ}C\), ethanol is \(78.4^{\circ}C\), and butanol is \(117.7^{\circ}C\). Since their boiling points are higher than room temperature (\(20 - 25^{\circ}C\)), they are all liquids at room temperature.

Answer:

D. all of the above
