Compare the boiling points of alcohol, ethers and alkanes and explain one reason for the difference
scoundrel [369]

Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.

<h3>What is meant by Boiling Point ?</h3>

The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.

Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C

The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.

The OH group in  alcohol allows molecules to engage in hydrogen bonding.

Therefore Boiling point are in the order ;

Alcohol > alkane > ethers

A student heats the same amount of two different liquids over Bunsen burners. Each liquid is at room temperature when the studen
ZanzabumX [31]

If Liquid 1 has a higher specific heat than Liquid 2, then Liquid 1 will take longer to increase in temperature because the higher specific heat of a liquid needs more thermal energy for heating a liquid.

<h3>What is specific heat?</h3>

Specific heat of a substance refers to the quantity of heat that is required to raise the temperature of one gram of a substance by one Celsius degree so we can conclude that  Liquid 1 will take longer to increase in temperature
