b. ethane (C2H6), a nonpolar covalent compound

Explanation:

The substance that would most likely need to cool to the lowest temperature before it condenses is ethane, a non-polar covalent compound.

Ethane in liquid form has very weak attractive forces binding the molecules together.

To form and change state, all the molecules must be brought very close together under very high pressure and low temperature. Else, they will not attract one another.

Ionic crystal lattice forces as seen in KBr are strong attractive forces. As a substance such as KBr begins to condense, they begin to attract one another with a very strong force even before they cool to their least temperature.
Ammonia has strong intermolecular hydrogen bonds in its structure which binds them together. The attraction is great between the hydrogen of one molecule and the nitrogen of another.
In ethane we have a weak attraction.

Some volatile organic compounds can be detected by hydrogeologists in the field or labs because of the ______ emitted from the g

Vadim26 [7]

Volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.

<h3>What are volatile substances?</h3>

Volatile substances are substances which can easily vaporize or change to gaseous state.

Volatile substances can either be solids or liquids but are mostly liquids.

Example of volatile substances include ether, petrol, chocolate.

The presence of volatile substances can be detected by the gases they release which may have characteristic odors.

Therefore, volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.

Draw structures from the following names, and determine which compounds are optically active:(b) 3-chloro-2,2,5-trimethylhexane

inn [45]

The given compound 3-chloro-2,2,5-trimethylhexane is an optically active compound .

Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .

It has chiral center.

Here the chiral carbon has 4 distinct groups such as : chlorine , hydrogen , 2-methylpropyl , tertbutyl .

<h3>What is di-symmetry?</h3>

Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .

<h3>Chiral center :</h3>

Have Sp3 hybridized center (4sigma bond ) .

4 distinct group is attached to the chiral atom. form non -superimposable mirror image .

<h3>What is optical isomerism ?</h3>

Same molecular formula and same structural formula . also have same physical and chemical properties .

They differ in their behavior towards plane polarized light (ppl) .
