Answer:
Water has the highest boiling point among the given options
Explanation:
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. At sea level, water boils at 100° C (212° F). The boiling points of the rest of the substances are Br2 = 58.8, C4H10 is -1 degrees C and NO2 is 21 °C. Therefore we can say that water is having the highest boiling point.
