b) Kutokana na fomula ya molekuli ya kiwanja kama C_3H_9N. Step 1: Tambua elementi zilizopo (b)(i) Fomula ya molekuli C_3H_9N inaonyesha wazi elementi zifuatazo: Kaboni (C) Hidrojeni (H) Nitrojeni (N) Elementi: Kaboni, Hidrojeni, Nitrojeni Step 2: Kokotoa Kiwango cha Kutokujitosheleza (Degree of Unsaturation - DU) na tambua aina za amini (b)(ii) Fomula ya molekuli ni C_3H_9N. Kiwango cha Kutokujitosheleza (DU) huhesabiwa kwa kutumia fomula: DU = C - (H)/(2) + (N)/(2) + 1 Ambapo C ni idadi ya atomi za kaboni, H ni idadi ya atomi za hidrojeni, na N ni idadi ya atomi za nitrojeni. DU = 3 - (9)/(2) + (1)/(2) + 1 DU = 3 - 4.5 + 0.5 + 1 DU = 0 DU ya 0 inaonyesha kuwa kiwanja hicho kimejitosheleza (hakina pete au vifungo viwili/vitatu). Kwa hiyo, miundo yote itakuwa ya mnyororo wazi. Hizi zitakuwa amini za msingi, sekondari, au tersia. Step 3: Chora fomula za miundo zinazowezekana (b)(ii) Kuna fomula nne zinazowezekana za kimuundo kwa C_3H_9N: 1. Propylamine (1-aminopropane): CH_3-CH_2-CH_2-NH_2 2. Isopropylamine (2-aminopropane): CH_3-NH_2|CH-CH_3 3. Ethylmethylamine (N-methylethanamine): CH_3-CH_2-NH-CH_3 4. Trimethylamine (N,N-dimethylmethanamine): CH_3-CH_3|N-CH_3 That's 2 down. 3 left today — send the next one.
