a.
CH4 + Cl2 --h.niu--> CH3Cl + HCl
CH4 + 2Cl2 --h.niu--> CH2Cl2 + 2HCl
CH4 + 3Cl2 --h.niu--> CHCl3 + 3HCl
CH4 + 4Cl2 --h.niu--> CCl4 + 4HCl
b.
3 utilizari CH4:
obtinerea de acetilena,
combustibil casnic,
obtinerea de HCN
2 utilizare CHCl3
solvent nepolar
agent de alchilare
2 utilizari CH2Cl2
solvent, anestezic
c.
x x moli
CH4 + Cl2 --h.niu--> CH3Cl + HCl
2x 2x moli
CH4 + 2Cl2 --h.niu--> CH2Cl2 + 2HCl
3x 3x moli
CH4 ----------------------> CH4 netransformat
403,2/22,4 = 18 moli
=> x+2x+3x = 18 => 6x=18 => x=3
CH4 reactionat x+2x = 3x = 9 moli
=> V = 9x22,4 = 201,6 L
