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

Answer
Tectonic plates are parts of the earth's crust. There are cracks in these plates that allow magma to seep through and build-up which creates volcanic eruptions. Volcanos themselves are created by the earth's plates pushing against each other and slowly, over time, rising to create these large raises in the crust. Earthquakes are caused by these plates creating friction against one another until they forcefully overlap or rip apart, hence the shaking effect during an earthquake.
Answer:
d = 0.793 g/L
Explanation:
Given data:
Density of fluorine gas = ?
Pressure of gas = 0.554 atm
Temperature of gas = 50 °C (50+273.15K = 323.15 K)
Solution:
Formula:
PM = dRT
M = molar mass of gas
P = pressure
R = general gas constant
T = temperature
d = PM/RT
d = 0.554 atm × 37.99 g/mol / 0.0821 atm.L /mol.K × 323.15 K
d = 21.05 atm.g/mol/26.53 atm.L /mol
d = 0.793 g/L
Answer:
true because the bonds cannot be broken down
