The temperature of evaporation is much higher for water than for alcohol. without knowing more about the chemistry of alcohol, which of the following is the most logical chemical explanation for this phenomenona. ionic bonds form between alcohol molecules. b. alcohol has a higher surface tension than water. c. fewer hydrogen bonds form between alcohol molecules.

C

Explanation:

Alcohols are organic molecules characterized majorly by the presence of the OH group in their molecule. The OH group is majorly responsible for several of their characteristics. This include the formation of hydrogen bonds between alcohol molecules. While this makes them more inorganic than most organic compounds, comparatively the hydrogen bonding formed in alcohols is not as strong as that which is present in water.

The higher strength of the hydrogen bonding is responsible for some comparable properties. While water boils at a temperature of 100 degrees Celsius, alcohol boils at a temperature of 78 degrees Celsius. This is an evidence to the fact that hydrogen bonding in alcohol is less stronger that that in water.

First thing to do is to calculate the amount in moles CO used for the combustion process. Then, we use the data from the reaction to determine the amount of heat released by that amount. We calculate as follows:

14 g ( 1 mol / 28.01 g ) = 0.50 mol CO

0.50 mol CO ( 67.6 kcal / 1 mol CO ) = 33.79 kcal 

Therefore, the closest from the choices listed is the third option.
