Question 34 (3 points) Rank the following compounds from largest Rf (on the left) to smallest...
Rank the following compounds from largest RF (on the left) to smallest Rf (on the right) in a TLC run with hexanelethyl acetate mobile phase. OH Di O I>II>11 ||I>II> 111>I>II 11>I>I|| A reaction was carried out between maleic anhydride (MA) and anthracene (A). The final reaction mixture (R) and samples of both starting materials were spotted on a TLC plate and run. Which plate shows that the reaction mixture contains a new product and maleic anhydride as excess reagent?...

A compound has the empirical formula of C7H15CIO. The 'H NMR integration values are 1=57. I=133, III=95. . What are the actual number of each hydrogen atoms? 1-3, 11=7, II=5 1=4, II=8, I=5 1-3, II=8, III=4 1=4, I1=6, III=5 Question 4 (3 points) Rank the following compounds from largest Rf (on the left) to smallest Rf (on the right) in a TLC run with hexane/ethyl acetate mobile phase. OH OH 11 III.
1. Rank the compounds in each group, groups l- IV, (1 - highest Rf value, 3-lowest Rf value) on a TLC plate run using a 1:1 hexanes:ethyl acetate as an eluent. (3 pts) Group l: OH Group ll: HN HO Group IlI: NH2 NH2 NO2 NO2 Group IV: он
Rank the following compounds from largest to smallest according to their expected magnitude in lattice energy. Rank from largest to smallest lattice energy To rank items as equivalent, overlap them. Cs1 KI MgS KBr BeO Largest Lattice Energy Smallest Lattice Energy
Referring back to question 5 above, in the TLC plate on the left the eluting mobile phase solvent was ethyl acetate, in the plate on the right it was 97% ethyl acetate and 3% methanol. Explain why the Rf values in the plate on the right are larger than those in the plate on the left. Your explanation must be in the terms of intermolecular forces, you are not allowed to only use the word "polarity". There are THREE dynamical...
