1.Precizati afirmatiile corecte referitoare la o solutie de acid acetic de concentratie 6%:

d.contine 0,001 moli de acid acetic dizolvat intr-un cm3 de apa.
e.contine 1 mol de acid acetic intr-un kg de solutie.
Ca raspunsuri corecte dau A,C,E. Insa mie mi se pare ca si D-ul e corect luand densitatea apei 1g/cm3. Explicatie de ce nu ar fi?
2. acidul 2-fenilacetic este considerat acid aromatic?
3. Precizati care dintre formulele moleculare enumerate mai jos pot corespunde unui compus din clasa fenolilor.
Raspuns corect:A,B,E. De ce C-ul nu e bun?
4.Am gasit intr-o grila data ca falsa afirmatia: Valorile constantelor de bazicitate ale aminelor nu depind de temperatura. E corect?
5.In alta grila reactia 2-butanamina + HNO2 + HCl= 2-butanol+N2+ H2O e data ca raspuns corect.Eu am considerat ca reactia e incorecta pentru ca la produsi clorul nu mai apare. Se poate neglija?
6. Resturile alchil sunt doar cele care provin de la alcani? Adica,de exemplu, radicalul Ar-CH2- nu este alchil? Daca nu,atunci e considerat aril?
7.Care dintre urmatoarele alchene prezinta izomeri cis-trans:
Raspuns corect:B,C,D. de ce nu e luat si E-ul? Stiam ca alchenele care prezinta la cei 2 atomi de carbon dublu legati acelasi substituent izomerii lor geometrici se pot numi si cis-trans. In cazul E, sunt doi radical etil identici.
We spent a lot of time at her home. Maybe so her mother could keep an eye on us. Mrs. Spencer made sure to be around, offering drinks, snacks, chit chat. I noticed that she was fairly young herself. Granted at my age, anyone over 25 was old, but she was probably mid-30s, divorced. If she was a indiction of how Carley would develop, maybe I should wait. Mrs. Spencer had fuller breasts and a nice butt. She appeared to be in great shape for her “advanced” age. I knew she was keeping an eye on me as much as I was on her and her younger daughter. Her eldest, Sharon was away at college at the time. With Mrs. Spencer around we mostly limited ourselves to holding hands and sneaking in a few light kisses. One day Mrs. Spencer caught us by surprise walking in as I’d slid my hand up from Carley’s stomach to rub her right breast through her shirt. She didn’t really need a bra yet, so I could feel her nipple, hard, through her shirt. Just this much contact had me hard also.
Really a good deal of useful knowledge.
