Acidic substances are substances that are capable of dissociating in solution to form a solution of protons and an anion. Update: glycine is amphoteric: it can either act as a base or an acid. going down the group electronegativity decreases. Chloroacetic acid is stronger acid than bromoacetic acid. (28-C (3) Outline a detailed mechanism for the acid catalyzed hydration of 2-methyl-2-butene and name the major product according to the IUPAC rules. 2-Chloroacetic acid is more acidic than acetic acid. Hence Cl > Br in terms of electron withdrawing effect (-I effect) Once a proton is lost chloroacetate and bromoacetate are formed Phenol Acetic acid Chloroacetic acid. Hence Cl is more electronegative than Br. Electron withdrawing atoms or groups at alpha carbon atom increases stability of the carboxylate anion by dispersing the charge.Hence acidic nature also increases. I think this is the main reason of the acidicity difference, since the pKa's are similar (comparing glycine and chloroacetic acid). Thus fluoro acetic acid is more acidic than chloro acetic acid. Inductive effect is responsible for the acidity of chloroacetic acid . Fluroacetic acid is more acedic than chloroacetic acid. Formula of chloroacetic acid is \(ClCH_2COOH\) Here, H atom is replaced by highly electron withdrawing Cl atom. Phenol is more acidic than ethanol because in phenol, the phenoxide ion obtained on deprotonation is stabilized by resonance which is not possible in case on ethanol. Glycine hydrochloride is the amino acid glycine adsorving a molecule of Hydrochloric acid, wich is a strong acid. So, the negative charge density on O atom reduced and corresponding conjugate base is stabilised.. Thus, the acid strength of the acid increases. 1 eq HI CH H3C-c-O-CH CH₂ The correct order of increasing acidic strength is Ethanol . Chloroacetic acid is also used in the production of phenoxy herbicides by etherification with chlorophenols. So now the H+ atom can easily come out and the stability of the carboxylate ion has also increased. So, chloroacetic acid is stronger than acetic acid. It is the precursor to the herbicide glyphosate and dimethoate. So now the H+ atom can easily come out and the stability of the carboxylate ion has also increased. Define the concept of the inductive effect. In this way 2-methyl-4-chlorophenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid, and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) are produced. Hence both the conditions make chloroacetic acid more acidic than acetic acid. (5) Propose a detailed mechanism for the following reaction. Why? The stronger the ewg (electron withdrawing group), the more acidic the compound. Thus, the acid strength of the acid increases.
