4. Reacţiile de adiţie la alchene decurg cu scindarea legăturilor: a)  C-C b)  C-C c)  C-C şi  C-C d)  C-H 5. Clorura de vinil (CH 2 =CH-Cl) este un monomer important pentru obţinerea policlorurii de vinil din care se fabrică piele artificială. Se cere: a) scrierea ecuaţiei reacţiei chimice b) masa molară medie a polimerului dacă gradul de polimerizare n=1000 c) cantitatea de clorură de vinil necesară obţinerii a 100kg polimer dacă randamentul de reacţie este  = 80% 6. Prin arderea a 4 moli dintr-o alchenă se consumă 18 moli oxigen. Identifică alchena. Mase atomice: C-12, H-1, Cl-35,5
