"carcinogenic"係可能致癌定係可以致癌? :icon101:
佢唔會咁考你下話:icon101:
自從我阿sir既一句話,我已經將目標由<2005年最後一隻E>升為<2005年最後一隻D>

乜野話 :confused:
自從我阿sir一句"拎B應該冇問題", 我拎A既信心就大左好多...
點知第二日2003 AL chem既成績... 令我既信心跌到落新低 :icon100:

好野喎,咁都拆到:icon082:
CHEM漸入佳境既同時,相反BIO陷入困境

本野真係叫chem-is-try :icon101:
一早叫你攻chem同phy架啦 :icon088:
bio... 唯有寫多D野落去, 例如兩分就寫四個pt

考完MOCK對卷,阿SIR話"你班友都係徘徊係E同F既邊緣架喇":icon101:
雖然話我未因為MOCK而係試前衝番一次,但以我PAIR左咁耐,我諗而家要背晒咁多野入腦真係唔易,起碼保住隻D先,再向C進發
PHY就聽食蕉架喇,今日對住本BEYOND 2000完全唔X識做,BK 2又冇史撈唇先死喎

佢advise我地買chem-is-try既phy chem...
不過我買埋其他兩本 (organic, inorganic + chem & soc)

我chem sir完全冇叫過我地買d exercise做,可能佢覺得做pp都夠
佢係chem堂既口頭禪係"有乜咁難呀","問啦",俾佢吹漲:icon082:
有個大問題... help!
2003年Paper II
No.7(b)(iii)
係問點樣將benzene變做diphenylmethane... (一個carbon連住兩個H同埋兩個benzene ring)
marking scheme就用左3個step...
佢隔離就寫左D野... 係用一個step, reagents係chlorophenylmethane同埋FeCl3 (即係alkylation)
跟住就話"without Lewis acid = 0"
我想問Lewis acid係咪即係個halogen-carrier(FeCl3)?
同埋如果加chlorophenylmethane + FeCl3, 呢個conversion得唔得?
因為我就係用chlorophenylmethane架AlCl3...
呢題野成3分架 :icon099:
thx~~~
