In an experiment, two unknown compounds (one an ether and the other an amine) of equal molecular mass were dissolved in water. the result of the experiment is shown in the table.
solubility comparison
unknown compound solubility (g/100 ml water)
a 4
b 0.25
which of the following correctly explains the identity of compound a and its solubility?
it is an amine; it contains a nitrogen atom that will allow nitrogen-hydrogen bonds to form while in water.
it is an ether; because the oxygen atom is within the carbon chain, so it is free to form oxy-hydrogen bonds to make it more soluble.
it is an ether; the high polarity of the oxygen-hydrogen bond makes it more soluble.
it is an amine; because the lower electronegativity of n than h makes it more soluble.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
