Now, it is time to think about how the structure of different organic groups contributes to their relative acidity or basicity, even when we are talking about the same element acting as the proton donor/acceptor. Although these are all minor resonance contributors (negative charge is placed on a carbon rather than the more electronegative oxygen), they nonetheless have a significant effect on the acidity of the phenolic proton. This also contributes to the driving force: we are moving from a weaker (less stable) bond to a stronger (more stable) bond. We must consider the electronegativity and the position of the halogen substituent in terms of inductive effects. 1. a) Draw the Lewis structure of nitric acid, HNO3. In the previous section we focused our attention on periodic trends – the differences in acidity and basicity between groups where the exchangeable proton was bound to different elements. Order of decreasing basic strength is. Looking at the conjugate base of phenol, we see that the negative charge can be delocalized by resonance to three different carbons on the aromatic ring. The lone pair on an amine nitrogen, by contrast, is not so comfortable – it is not part of a delocalized pi system, and is available to form a bond with any acidic proton that might be nearby. HI, with a pKa of about -9, is almost as strong as sulfuric acid. Periodic Trend: Electronegativity. Therefore, it is the least basic.
The first model pair we will consider is ethanol and acetic acid, but the conclusions we reach will be equally valid for all alcohol and carboxylic acid groups. So therefore it is less basic than this one. Consider first the charge factor: as we just learned, chloride ion (on the product side) is more stable than fluoride ion (on the reactant side). In the other compound, the aldehyde is on the 3 (meta) position, and the negative charge cannot be delocalized to the aldehyde oxygen. The acidity of the H in thiol SH group is also stronger than the corresponding alcohol OH group following the same trend. The sp3 hybridization means 25% s character (one s and three p orbitals, so s character is 1/4 = 25%), sp2 hybridization has 33. B: Resonance effects. Vertical periodic trend in acidity and basicity. This means that anions that are not stabilized are better bases. The more electronegative an atom, the better able it is to bear a negative charge.
This can also be stated in a more general way as more s character in the hybrid orbitals makes the atom more electronegative. The resonance effect also nicely explains why a nitrogen atom is basic when it is in an amine, but not basic when it is part of an amide group. The chlorine substituent can be referred to as an electron withdrawing group because of the inductive effect. When moving vertically in the same group of the periodic table, the size of the atom overrides its EN with regard to basicity. Notice that the pKa-lowering effect of each chlorine atom, while significant, is not as dramatic as the delocalizing resonance effect illustrated by the difference in pKa values between an alcohol and a carboxylic acid.
C: Inductive effects. By clicking Sign up you accept Numerade's Terms of Service and Privacy Policy. The strongest base corresponds to the weakest acid. The only difference between these three compounds is a negative charge on carbon versus oxygen versus nitrogen. Therefore phenol is much more acidic than other alcohols. In the carboxylate ion, RCO2 - the negative charge is delocalised across 2 electronegative atoms which makes it the electrons less available than when they localised on a specific atom as in the alkoxide, RO-. Note that the negative charge can be delocalized by resonance to two oxygen atoms, which makes ascorbic acid similar in strength to carboxylic acids. A CH3CH2OH pKa = 18. Answered step-by-step. Key factors that affect the stability of the conjugate base, A -, |.
The only difference between these three compounds is thie, hybridization of the terminal carbons that have the time. Electronegativity but only when comparing atoms within the same row of the periodic table, the more electronegative the anionic atom in the conjugate base, the better it is at accepting the negative charge. The element effect is about the individual atom that connects with the hydrogen (keep in mind that acidity is about the ability to donate a certain hydrogen). What makes a carboxylic acid so much more acidic than an alcohol. Key factors that affect electron pair availability in a base, B. More importantly to the study of biological organic chemistry, this trend tells us that thiols are more acidic than alcohols. However, the pK a values (and the acidity) of ethanol and acetic acid are very different.
Solution: The difference can be explained by the resonance effect. Do you need an answer to a question different from the above? After deprotonation, which compound would NOT be able to.
Weaker bases have negative charges on more electronegative atoms; stronger bases have negative charges on less electronegative atoms. Look at where the negative charge ends up in each conjugate base. Notice, for example, the difference in acidity between phenol and cyclohexanol. At first inspection, you might assume that the methoxy substituent, with its electronegative oxygen, would be an electron-withdrawing group by induction.
The ketone group is acting as an electron withdrawing group – it is 'pulling' electron density towards itself, through both inductive and resonance effects. In addition, because the inductive effect takes place through covalent bonds, its influence decreases significantly with distance — thus a chlorine that is two carbons away from a carboxylic acid group has a weaker effect compared to a chlorine just one carbon away. Hint – try removing each OH group in turn, then use your resonance drawing skills to figure out whether or not delocalization of charge can occur. This one could be explained through electro negativity alone. As stated before, we begin by considering the stability of the conjugate bases, remembering that a more stable (weaker) conjugate base corresponds to a stronger acid. Because the inductive effect depends on electronegativity, fluorine substituents have a more pronounced pKa-lowered effect than chlorine substituents. This is consistent with the increasing trend of EN along the period from left to right.
