Mavzu : 7-nazorat ishi. Aminlar, aromatik aminlar va nitrobirikmalar

O‘qituvchi: Lobar Boboqulova

Mavzu bayoni:

• 
  Masala: 45 g etilamin olish uchun qancha hajmdagi (n.sh.) vodorod gazi kerak bo’ladi?
  
• 
  Masala: Kimyoviy korxonada 41 g nitrobenzol yordamida 18,6 g anilin olingan bo’lsa, reaksiyaning unumini hisoblang.
  

x l 45g

C₂H₅NO₂ + 3H₂ → C₂H₅NH₂ + 2H₂O x — 45

67,2 — 45 x = 67,2litr Javob: 67,2 litr

41g 18,6g

C₆H₅NO₂ + 3H₂ → C₆H₅NH₂ + 2H₂O 41 — x

123 — 93 x = 31g

η = (18,6 * 31)/100 = 60% Javob: 60%

• 
  Masala: Murakkab efirning chiqish unumi 90% bo’lsa, 120 g sirka kislota va 138 g etanoldan necha gramm etilasetat olish mumkin? Javob: 158 g
  
• 
  Masala: Quyidagi o’zgarishlarni amalga oshiring
  

C₂H₆ → C₂H₅Cl → C₂H₅OH → CH₃COOH → CH₃COONa

C₂H₆ + Cl₂ → C₂H₅Cl + HCl

C₂H₅Cl + KOH → C₂H₅OH + KCl

C₂H₅OH + CuO → CH₃COH + Cu + H₂O

CH₃COH + Ag₂O → CH₃COOH + 2Ag↓

2CH₃COOH + 2Na → 2CH₃COONa + H₂↑

II-variant

• 
  Masala: 21,7 g metilamin olish uchun qancha hajmdagi (n.sh) vodorod gazi kerak bo’ladi?
  
• 
  Masala: Kimyoviy korxonada 82 g nitrobenzol yordamida 60 g anilin olingan bo’lsa, reaksiyaning unumini hisoblang.
  
• 
  Masala: 40% li natriy ishqorining 200g metilasetat bilan ta’sirlashuvidan necha gramm spirt hosil bo’ladi?
  
• 
  Masala: 46 g anilinni to’liq bromlah uchun qanday massadagi (g) brom sarflanadi?
  

Uyga vazifa: II-variant nazorat ishi masalalarini yechish
