Learn the basics about the principle of green chemistry that considers reducing derivatives, as a part of environmental chemistry.
Functional groups are the sites in a molecule where a reaction occurs. Some molecules may have more than one functional group which may be a problem if you’re carrying out a reaction, but you only want the reaction to occur at one particular functional group.
To prevent the other functional groups from reacting, we must “protect” them. To do so, we must add a protecting group, or a derivative. These groups are also called blocking groups.
This can be an issue because it costs time and energy to add and remove these protecting groups.
Chemists, in an effort to be more environmentally friendly, are developing chemoselective methods and syntheses - this means that the reaction will happen only at a particular functional group.

In this video we’re going to look at how to simplify algebraic expressions. Before we get started on simplifying, a few things to remember:
(1) we always use a use a curly x for the letter x in algebra.
(2) We don’t really use the mul
In algebra, we replace a letter with numbers in the process known as substitution. Given the formula A = 1/2bh, if the base is 5cm and the height is 10cm, then the area is ½ X 5 X 10 because we have replaced the b with 5 and the h with 10. You just need to be be careful with negative numbers: it is
