✔ 最佳答案
CH3CH2OH與C6H12會產生 electrophilic addition (SN-1 type)

CH3CH2OH => (partially +ve)CH3CH2----OH(partially -ve)
CH3CH2+ 會attack C6H12既double bond位置形成branch chain
由於CH3CH2+加落C6H12會使C6H12變成+ve(係double bond果個C是+ve),OH-就會attack+ve果個位,使整個compound變成一隻Alkanol‧
由於你無講個double係邊個位,我話唔到比你知最後隻野係點,不過,只要係double bond果兩個C度,其中一個加CH3CH2做branch chain,而另一個則加OH就OKAY了‧
順帶一提,加OH果個C要連住多D carbon chain‧例如 :
CH3CH2(CH3CH2)CH2(OH)CH2CH2CH3
當中第二個C(由左到右)的括號內的CH3CH2是加成的branch chain,而第三個C則加OH‧這樣,加左OH果個C就連住CH2CH2CH3三個carbon,而加CH3CH2既就連住CH3一個carbon而已‧

明白了嗎 ?

I don't think this ethanol and cyclohexane will have any reaction. Also,the ethanol may even not soluble in cyclohexane.
