Interpretation:
Among the given molecules, which molecule has a different acidity than Y, is to be identified.
Concept introduction:
In order to be isomers, two compounds should have the same molecular formula.
Isomers are the molecules having same molecular formula but different structural formula or different configuration. Constitutional isomers must have different physical and chemical properties. In an achiral environment, enantiomers have exactly the same physical and chemical properties. In a chiral environment, enantiomers show different physical and chemical properties. Depending on a specific situation, the behavior of enantiomers can be slightly or dramatically different. Diastereomers show different physical and chemical properties. Enantiomers and diastereomers are configurational isomers of each other having the same connectivity.

- Draw Lewis structure for an isomer of C3H6O2 that is a carboxylic acid, and draw another Lewis structure for an isomer of C3H6O2 that is an ester.arrow_forwardThe base methylamine ( CH3NH₂) has a Kb of 5.0 x 10-4. A closely related base, trimethylamine ( (CH3)3N), has a Kb of 7.4 x 10-5. a Which of the two bases is stronger? methylamine trimethylamine Correct Since methylamine has the larger K₁, methylamine is the stronger base. b Calculate the pH of a 0.38 M solution of the stronger base. pH =arrow_forward78) Why are primary alcohols more acidic than tertiary alcohols, in general? Because tertiary alcohols have less acidic hydrogens. Because primary alcohols have less electron-donating groups which create more effective charge separation between oxygen and hydrogen atom, making it more acidic. Because primary alcohols are more polar than tertiary alcohols. Because primary alcohols have less electron-donating groups which decrease electron density on oxygen, making it more susceptible for H+ to depart from the structure.arrow_forward
- Are carboxylic acids or carboxylate ions more acidic? I'm confused about the terms and how to determine the acidity. Here is my current understanding: Carboxylic acids have the ability to donate a hydrogen ion and become deprotonated, therefore it is acidic. Carboxylate ions are already deprotonated and have already become acidic. Is this correct?arrow_forwardDraw the product formed when the Lewis acid (CH;CH),C* reacts with each Lewis base: (a) H20; (b) CH3OH; (c) (CH3)20; (d) NH3; (e) (CH3)2NH.arrow_forwardWrite the chemical equation for a pentanoate ion acting as base when it reacts with hydrochloric acid (HCI). Which is formula of this rule of reaction?arrow_forward
- When the conjugate acid of aniline, C6H5NH3+, reacts with the acetate ion, the following reaction takes place: C6H5NH3+(aq)+CH3COO(aq)C6H5NH2(aq)+CH3COOH(aq) If Kafor C6H5NH3+ is 1.35105 and Kafor CH3COOH is 1.86105 , what is K for the reaction?arrow_forwardIn each of the following reactions, two possible organic products can be formed. Draw both organic products in each case and then circle the one formed in greatest quantity in each case. HC (a) 1) NaH, 2) acid (b) CH,CH,OH (c) CH,CH,OH NH2 (d) Oarrow_forwardThe compound WH2(C5H5)2 acts as a base, but TaH3(C5H5)2does not. Explain.arrow_forward
- The normal pH range for blood plasma is 7.35–7.45. Under these conditions, would you expect the carboxyl group of lactic acid (pKa 3.08) to exist primarily as a carboxyl group or as a carboxylic anion?
