(a)
Interpretation:
From the given set of alcohols in the order of increasing solubility in water has to be arranged.
Concept Introduction:
Alcohols are soluble in water because it makes hydrogen bonding with water. If the length of the hydrocarbon chain is small it can easily overcome the hydrogen bonding with less energy so water solubility of alcohol increases. If the length of the hydrocarbon chain is long, then it requires more energy to overcome the hydrogen bonding so water solubility of alcohol decreases.
(b)
Interpretation:
From the given set of alcohols pentyl alcohol, 1-hexanol, ethylene glycol in the order of increasing solubility in water has to be arranged.
Concept Introduction:
Refer to part (a).

- Don't used hand raiting and don't used Ai solutionarrow_forwardGive the structure(s) of the product(s) the reaction below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity). Draw out relevant enantiomer(s) if they are expected to form. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise I'm struggling to see how this reaction will go! I am wondering if it will cycle on itself but I'm not sure how I drew out a decagon but I'm a bit lostarrow_forwardGive the structure(s) of the product(s) for the reactions below, and be sure to indicate any relative stereochemistry (you can assume that each of the Diels-Alder reactions will proceed with endo selectivity).
