Let's start with point before dash arithmetic. This rule says: Calculate multiplication and division first and then addition or subtraction. Using an example, we will now show how to apply this rule (and how to do it wrong).

Go through the example from before again. Then follow a number of other examples. Look at each one carefully and try to follow the calculation. And again, multiplication or division first, then addition or subtraction.

AlcoholsThe functional group of the substance class of alcohols is the hydroxyl group (OH group). Alcohols are thus formed by the substitution of at least one hydrogen atom with a hydroxyl group. If they are aromatic alcohols, they are also called phenols. They are formed when at least one hydrogen atom of an aromatic is replaced by a hydroxyl group. Alcohols

R/S nomenclature The official naming of enantiomers is done according to the so-called R/S nomenclature. Here, it is not the direction of rotation of polarized light that plays a role, as in the (+)- or (-)- form (see above), but the geometry of the stereocenter. To determine whether an enantiomer has the R- or S-form, proceed as follows:
