Cyclohexane (C6H12) is a hydrocarbon (a substance containing only carbon and hydrogen) liquid. Which of the following will most likely dissolve in cyclohexane to form a solution?

a) NaBr
b) CH2Cl2
c) CH3CH2CH2CH2CH3
d) HI

Option (c) is the correct answer.

Explanation:

It is known that like dissolves like. As cyclohexane is a hydrocarbon and we know that hydrocarbons are non-polar in nature. So, a non-polar compound will be soluble in a hydrocarbon.

For example, NaBr is an ionic compound and when it i added to liquid cyclohexane then it will not dissolve. Similarly, and HI are polar covalent compounds and they will not dissolve in liquid cyclohexane.

But is a non-polar compound. So, when it is added to liquid cyclohexane then it will readily dissolve.

Thus, we can conclude that pentane () will most likely dissolve in cyclohexane to form a solution.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
