NYS Regents Chemistry Review for Unit Test
What is higher due to a greater intermolecular force?
Boiling point increases with an increase in intermolecular forces
When potassium bromide dissolves in water, what will be attracted to the hydrogen end of the water molecule and Why?
will attract to the water end of the molecule because that end is positive and bromide is negatively charged.
What would cause a substance to have stronger dispersion forces than another?
The larger the molecule (so greater number of electrons) creates a greater dispersion force.
What type of force occurs between polar molecules?
What type of force exists between nonpolar molecules?
London dipsersion forces
Explain why water, although a very small molecule, is a liquid at room temperature.
Strong hydrogen bonding causes water to be a liquid.
Give 3 examples of nonpolar molecules that contain polar bonds
Give two examples of classic polar molecules
or HCl or HF
Explian why some solid substances are able to sublime. Use an example
(s) or CO
(s) are able to sublime due to the weak intermolecular forces (Dispersion)
Which organic would have the lower boiling point, butane or hexane? Explain
Butane because it is the smaller molecule and so would have weaker dispersion forces.
What bond type results in an unequal charge distribution in the molecule?
What force holds nitrogen molecules together in the liquid state?
The strongest hydrogen bonds are formed between molecules in which hydrogen is bonded to an element with ____ electronegativity and a ____ radius.
The strongest hydrogen bonds are formed between molecules in which hydrogen is bonded to an element with
electronegativity and a
What causes the strenghth of hydrogen bonding to increase?
Themore polar the molecule, the stronger the force.
What state of matter do each of the halogens exist at room temperature?
b) explain why this is in terms of intermolecular forces
: gas Cl
: gas Br
: liq I
b) the larger the molecule, the stronger the dispersion force
What forces exist between liquid Krypton atoms?
