What is the name of this hydrocarbon ?

a. di-ethylbutane
b. di-ethylpropane
c. methylpropane
d. methylpropene
e. methylpropyne

Option C is correct: methylpropane

Explanation:

Name of the given Structure = ?

Structure given: Shown in attachment

Naming organic compound

Select the longest chain: so it contain three carbonAs the compound is saturated that contain single bond in-between carbon atom so it is known as alkane. For three carbon atoms it is a propaneLook for the functional group: so, there is one methyl (CH₃) group attached at carbon number 2.So the name include methyl too.

Now the final name of this compound is methylpropane

So, option C is correct.

C. definite shape, definite volume. that is a solid.

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.
