Question
Which specific bonds of the following compounds arc polar covalent bonds? Draw vector-annotated three-dimensional diagrams to determine which compounds have a nonzero molecular dipole moment. A. CF_4 B. H_3COH C. H_3CCOCH_3 Rank each of the following lists from the most to least acidic compound. Describe your reasoning concisely and clearly. A. H_3CCO_2H, H_2SO_4, H_2O B. H_3CCH_2OH, H_3CCH_2NH_2, H_3CCO_2H C. HBr, HCl. HI Which solvent(s) (choices: water, a polar organic solvent, or a nonpolar organic solvent) would one use to dissolve each of the following compounds? Describe in detail what must occur at the molecular level for solute to dissolve. In particular, describe the specific interactions that are broken and those that are formed. Finally, draw annotated diagrams of the solvated solutes to illustrate your answer. A. KBr B. H_3CCH_2CH_2CH_2OH C. H_3CCH_2CH_2CH_2CH_2CH_2CH_2CH(CH_3)_2Explanation / Answer
5)
A) order of acidity: H2SO4 > CH3COOH > H2O (sulfuric acid is more acidic than acetic acid because of more dissociation of sulfuric acid in water.)
B) order of acidity: CH3COOH > CH3CH2OH > CH3CH2NH2 (carboxylic acids are more acidic than alcohols. Alcohols are more acidic than amines.)
C) order of acidity: HI > HBr > HCl (As the size of the anion increases the acidity increases due to weak bonding in hydrogen halides.)
