How co you find anhydrides?

Answer 1

In a catalogue, or in a chemistry store?

The word #"anhydride"# literally means #"without water"#; organic anhydrides have the general formula of #RC(=O)O(O=)CR'#, and are formed by the condensation reaction of two carboxylic acids or their derivatives:
#RC(=O)OH+R'C(=O)XrarrRC(=O)O(O=C)R' + HX#

This reaction can take many different forms.

Anhydrides can be identified through chemical tests, such as reaction with water to form corresponding acids or reaction with alcohols to produce esters. Analytical techniques like infrared spectroscopy and nuclear magnetic resonance can also be used for identification.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
