Explain how your experimental data for Rf values are, or are not, consistent with your predictions of enantiomeric and diastereomeric relationships between the menthol stereoisomers. What other data do you have for these compounds that support your predictions

Answer is explained below.

Explanation:

As (+) menthol and (-) menthol are enantiomers whose physical properties are same except optical activity so we can expect they have similar Rf values.

Whereas diastereomers have different physical properties and different Rf values.

For example when the (+) menthol , (-) menthol, isomenthol and neomenthol undergo TLC (thin layer chromatography) the

Rf values of.(+menthol) = .447

Rf (+isomenthol) = .395

Rf (+neomenthol)= .487

Rf (-menthol) = .434

The above data shows that (+) menthol and (-) menthol have almost same Rf values and vary a little i.e 0.447 and 0.437. So we can conclude them as enantiomers

Whereas (+) menthol or (+) neomenthol or (+) isomenthol i.e 0.447 , 0.395 and 0.487 have different Rf values. We can conclude them as diasteromers.

(+) menthol and (-) menthol - enantiomers

(+) menthol and (+) neomenthol- diastereomers

(-) menthol and (+) isomenthol - diastereomers

Question is incomplete, complete question is as follows:

Explain how your experimental data for Rf values are, or are not, consistent with your predictions of enantiomeric and diastereomeric relationships between the menthol stereoisomers. What other data do you have for these compounds that support your predictions

Results from Lab:

Rf (+menthol) = .447

Rf (+isomenthol) = .395

Rf (+neomenthol)= .487

Rf (-menthol) = .434

(+) menthol and (-) menthol are enantiomers  (because they both have almost same Rf values and vary a little i-e 0.447 for (+menthol) and 0.434 (for - menthol) hence declared as enantiomers)

(+) menthol and (+) neomenthol are diastereomers (As they have different Rf values )

(-) menthol and (+) isomenthol are also diastereomers (They also have different Rf values)

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.
