A7 The intermolecular attractive forces between two salicylic acid molecules (structure for one molecule shown below) are: ОН ОН (A) Dispersion forces alone (B) T-t (pi-pi) interactions alone (C) Hydrogen bonding alone (D) Dispersion forces and hydrogen bonding (E) Dispersion forces, -T (pi-pi) interactions and hydrogen bonding
Propose a structure for the polymer formed by intermolecular reaction of salicylic acid during the synthesis of aspirin. Which is the stronger acid, aspirin or salicylic acid?
2. A structure of Luminol is shown with all functional groups protonated and their pka labeled. Use words and structures to answer a and b. Luminol pke 2 9 a. Acetic acid was added at the end of the reduction step to obtain a pH of - 3-4.2pts i. Draw the structure of the luminol at pH 3. ii. Refering to the structure in a.i.), explain why the luminol precipitates from the aqueous solution at this pH. NH₂ NH N-H...
Select the single best answer. Explain in terms of intermolecular forces the following: Why NaCl has a higher melting point than 12 Because NaCl is soluble in water, and I, is not. Because NaCl is an ionic compound, and the ion-ion attractions are much stronger than the dispersion forces between the I, molecules. Because NaCl is a solid, and I, is a liquid. Because NaCl can form hydrogen bonds, and I cannot.
For 3-Hydroxypropanoic Acid(pKa= ? ): a)Find the approximate pKa value for each compound and draw the structure of each compound and its conjugate base, b) Circle the form (acid or base) that predominates at a pH of 7 c)Write whether the predominate form would be more water soluble or more organically soluble.
Based on their composition and structure, list CH3ClCH3Cl, CH3CH2CH3CH3CH2CH3, and CH3CH2OHCH3CH2OH in order of decreasing intermolecular forces. Explain why

H2A is a diprotic acid of which pKa values are 3.0 and 7.0.
Answer to the following questions.
(a) The pH of an aqueous solution prepared by dissolution of HzA can be approximately calculated by assuming that H2A is a monoprotic acid. Explain why this assumption is valid in terms of equilibrium constant and fractional composition. (10 pt)
Is KHTar more soluble in water or in 0.10M NaNO3? Explain in terms of the intermolecular forces experienced by the solute ions.
1. Explain why the salicylic acid is insoluble at RT and soluble at high temperatures (when hot)? -Explanation should include what is occurring/ happening in molecular level. -Your answer should be concise and should not exceed 100 words (please note that , if it is too long it will not be graded)
