2-HALOGENI (17. skupina)

Question 1

F + voda

F je najmočnejši OKSIDANT

Answer 1

2 F2 + 2 H2O → 4 HF + O2

Question 2

Cl IND: elektroliza NaCl

Answer 2

2 NaCl → 2 Na + Cl2

2 Cl- - 2e- → Cl2

Question 3

DEACONOV POSTOPEK

oksidacija HCl s kisikom

Answer 3

4 HCl + O2 → 2 Cl2 + 2 H2O

katalizator CuCl2, T=430°C

Question 4

Cl LAB: oksidacija HCl + KMnO4

poskus

Answer 4

2 KMno4 + 16 HCl → 5 Cl2 + 2 KCl + 2 MnCl2 + 8 H2O

poskus

Question 5

Cl LAB: oksidacija HCl + klorovo apno CaCl(ClO)

Answer 5

CaCl(ClO) + 2 HCl → Cl2 + CaCl2 + H2O

Question 6

Br IND:

kloriranje lužin

Answer 6

2 Br- + Cl2 → 2 Cl- + Br2

Question 7

Br LAB: oksidacija bromidov z MnO2 (v kislem)

Answer 7

2Br(-) + MnO2 + 4H(+) → Mn(2+) + Br2 + 2 H2O

Question 8

I LAB: isto ko brom

Answer 8

2I(-) + MnO2 + 4H(+) → Mn(2+) + I2 + 2 H2O

Question 9

F2 z vodikovimi spojinami

H2S

Answer 9

H2S + F2 → S + 2 HF

Question 10

F2 z vodikovimi spojinami

NH3

Answer 10

2 NH3 + 3F2 → N2 + 6 HF

Question 11

X + H2S

Answer 11

H2S + Cl2 → 2 HCl + S

Question 12

Fe segrejemo, dodamo Cl2

Answer 12

2 Fe + 3 Cl2 → 2 FeCl3 (oranžno rjav dim)

Question 13

H in Cl verižna reakcija UV, T

Answer 13

Cl2 → 2 Cl

Cl + H2 → HCl + H
H + Cl2 → HCl + Cl

H + H → H2
Cl + Cl → Cl2

Question 14

Cl2 in spojine s H

H2S

Answer 14

H2S + Cl2 → 2 HCl + S

Question 15

Cl2 in spojine s H

CH4

Answer 15

CH4 + Cl2 → HCl + CH3Cl

Question 16

Cl2 in spojine s H

C2H2

Answer 16

C2H2 + Cl2 → 2 C + 2 HCl
