以下係困擾我多年的問題:

1)Phenol group(Ar-OH) 同 halogen group (-X) 算唔算係 funtional group?
如果phenol group 係.咁benzene ring 係唔係?

2)AL2000 paper 2 1(a)(ii)(||)唔明點計

3)AL2000 paper 2 4(d)(iii)畫既 vapour pressure - liquid composition 同 vapour composition curve 點解一個係直, 一個係曲

4)Ideal solution 的boiling point - composition curve 得一條直線, 但係點解fractional distillation 中ideal solution的 boiling point - composition curve有liquid 同vapour curve,重要係一條concave upwards,一條concave downwards?點分幾時直幾時曲?

5)一d experiment(好似estericfication, oxidation of alcohol, distillation 等)點知幾時用open system 同closed system?

6)Hardening of vegetable oil 既eqt 入面的vegetable oil 係
CH2OOCH2R
|
CHOOCH2R'
|
CH2OOCH2R''

定係
CH2COOR
|
CHCOOR'
|
CH2COOR''?
因為我睇書(NEW WAY CHEM BK 4 P.296)係後者,但oil乜唔係前者咩?

7)想問AL CHEM 寫chemical equation 係咪一定要寫埋state?

8)點解test carboxylic acid 時ester formation 之後要加sodium carbonate?

9)Catalytic hydrogenation 要唔要high temperature or high pressure?

10)Cellulose的polymer showing one repeating unit 應該係有1舊glucose unit定2舊?

THX!
