Huu hapa ni utatuzi wa maswali yako:

a) Taja mchakato katika hatua:

  • I: Propanol huungua kabisa na kutoa kaboni dioksidi na maji. Mchakato: Mwako kamili
  • III: Propanol humenyuka na asidi methanoiki kuunda esta. Mchakato: Uundaji wa esta (Esterification)
  • IV: Propanol huoksidishwa na kuwa asidi propanoiki. Mchakato: Uoksidishaji

b) Andika mlinganyo wa mmenyuko katika hatua:

  • I: Mwako kamili wa propanol. 2CH3CH2CH2OH(l)+9O2(g)→6CO2(g)+8H2O(g)\text{2CH}_3\text{CH}_2\text{CH}_2\text{OH}(l) + \text{9O}_2(g) \rightarrow \text{6CO}_2(g) + \text{8H}_2\text{O}(g)
  • V: Asidi propanoiki humenyuka na hidroksidi ya sodiamu. CH3CH2COOH(aq)+NaOH(aq)→CH3CH2COONa(aq)+H2O(l)\text{CH}_3\text{CH}_2\text{COOH}(aq) + \text{NaOH}(aq) \rightarrow \text{CH}_3\text{CH}_2\text{COONa}(aq) + \text{H}_2\text{O}(l)

c) Toa jina na fomula ya kimuundo ya dutu M:

  • Dutu M huundwa kutokana na propanol na asidi methanoiki. Jina: Propyl methanoate Fomula ya kimuundo: HCOOCH2CH2CH3\text{HCOOCH}_2\text{CH}_2\text{CH}_3

d) Taja kirejeshaji:

  • B: Kirejeshaji kinachooksidisha propanol kuwa asidi propanoiki. Kirejeshaji: Potasiamu dichromate(VI) iliyotiwa asidi au Potasiamu permanganate(VII) iliyotiwa asidi
  • N: Kirejeshaji kinachobadilisha sodiamu propanoate kuwa ethane kupitia mmenyuko wa dekarboksilesheni. Kirejeshaji: Soda lime (NaOH/CaO\text{NaOH}/\text{CaO})
