While carbon C and hydrogen H form the foundation of organic molecules, the rich diversity and specificity of interactions between biological and drug molecules arises from the presence of heteroatoms N, O, S, P, halides when they combine with C and H to form various functional groups.

2.10: Organic Acids and Organic Bases

This page explains the acidity of simple organic acids and looks at the factors which affect their relative strengths. For the purposes of this topic, we are going to take the definition of an acid as "a substance which donates hydrogen ions protons to other things". We are going to get a measure of this by looking at how easily the acids release hydrogen ions to water molecules when they are in solution in water. A hydronium ion is formed together with the anion negative ion from the acid. This equilibrium is sometimes simplified by leaving out the water to emphasize the ionization of the acid. If you write it like this, you must include the state symbols - " aq ".

You may wish to review this topic before proceeding. Here, acids are defined as being able to donate protons in the form of hydrogen ions; whereas bases are defined as being able to accept protons. This took the Arrhenius definition one step further as water is no longer required to be present in the solution for acid and base reactions to occur. The Arrhenius theory where acids and bases are defined by whether the molecule contains hydrogen and hydroxide ion is too limiting. This is best illustrated in the following equation:. In the case of the HOH it is a base in the first case and an acid in the second case. To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction.

Introduction to Acid-Base Reactions. In the first post I made introducing acid base reactions , I just said that the first order of business is just to figure out the bonds that form and the bonds that break, and recognize the four components. Like this. We have names for each of the species involved:. For instance, why does the above reaction proceed well, but the reaction below does not? Here are four sample acid-base reactions. If you read about the stability of negative charge earlier, you should be able to gauge which of these will be more favorable and which are less favorable.

Acid Base Reactions In Organic Chemistry

An acid—base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. Their importance becomes apparent in analyzing acid—base reactions for gaseous or liquid species, or when acid or base character may be somewhat less apparent. The first of these concepts was provided by the French chemist Antoine Lavoisier , around It is important to think of the acid-base reaction models as theories that complement each other.

First of all, back to the shepherds :. Oxygius, having six sheep to take care of, found he could make a bargain with two of the Hydrus shepherd boys, whom each brought a sheep of their own. In so doing, Oxygius fulfilled his commitments under the law of Emperor Octavius, and each of the Hydrus shared the tending of a pair of sheep with Oxygius. One day one of the Hydrus shepherd boys told Oxygius he wanted to leave the arrangement. He wanted to take his lone sheep and explore some of the lands on distant hillsides, as he used to do before he met Oxygius.

Или надумает продать кольцо. Беккер не мог ждать. Он решительно поднял трубку, снова набрал номер и прислонился к стене. Послышались гудки. Беккер разглядывал зал. Один гудок… два… три… Внезапно он увидел нечто, заставившее его бросить трубку.

Он вот-вот задавит. Уже теряя сознание, она рванулась к свету, который пробивался из приоткрытой двери гостиничного номера, и успела увидеть руку, сжимающую пистолет с глушителем. Яркая вспышка - и все поглотила черная бездна.

Но решил этого не делать. Сьюзан так и подумала. Старшие должностные лица АНБ имели право разбираться со своими кризисными ситуациями, не уведомляя об этом исполнительную власть страны. АНБ было единственной разведывательной организацией США, освобожденной от обязанности отчитываться перед федеральным правительством. Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине. Вам следовало бы привлечь кого-то .
