a. Un estereoisómero del 1,1,3,5-tetrametilciclohexano es 15 kJ/mol (3.7 kcal/mol) menos estable que el otro. Indicar cuál isóme
1 answer:
The cis isomer of 1, 1, 3, 5-tetramethylcyclohexane is more stable than the trans of 1, 1, 3, 5-tetramethylcyclohexane. This also implies that former has a higher stability and energy than the later.
<h3>Stable 1, 1, 3, 5-tetramethylcyclohexane</h3>The picture attached to this answer sheet is cis isomer of 1, 1, 3, 5-tetramethylcyclohexane
Also even, the cis isomer of 1, 1, 3, 5-tetramethylcyclohexaneexist in two forms
- Diaxial form

Answer:
0.5188 M or 0.5188 mol/L
Explanation:
Concentration is calculated as <u>molarity</u>, which is the number of moles per litre.
***Molarity is represented by either "M" or "c" depending on your teacher. I will use "c".
The formula for molarity is:
n = moles (unit mol)
V = volume (unit L)
<u>Find the molar mass (M) of potassium hydroxide.</u>
<u>Calculate the moles of potassium hydroxide.</u>
Carry one insignificant figure (shown in brackets).
<u>Convert the volume of water to litres.</u>
Here, carrying an insignificant figure doesn't change the value.
<u>Calculate the concentration.</u>
<= Keep an insignificant figure for rounding
<= Rounded up
<= You use the unit "M" instead of "mol/L"
The concentration of this standard solution is 0.5188 M.
