organic chemistry memang banyak hafal.....from the basic methane and the alkana group sampai ler alkena, alkohol, ester etc..etc
basically subject ni banyak deal dengan struktur dan ikatan karbon in betwen molecul..dan juga ciri-ciri kumpulan...contoh sume kumpulan alkohol ade rantai -OH ..termasuk juga double bond dan tripple bond...
ciri-ciri group dan juga sebatian aromatik dan tak aromatic...
biasa memang kena hafal bentuk2 rantai dan jenis-jenis rantai dan ikatan..sebagai contoh n-propanol tak sama dengan iso-propanol dari segi shape...
best ker tak?? depend dengan org..some suka some tak..aku memang x suka....sebab kena hapal dan juga experiment memang exposed to some unpleasant smell....

kimia fizikal deal dengan lot of stuff....from the basic of an atom, qualitative/quantitative calculation, chemical equlibrium etc..etc, the atom and the molucul, termasuk juga a bit of thermodynamics properties...
aku suka subject ni sebab banyak calculation dan juga facts..i love balancing an equalibrium..
subject ni jugak study about chemical reaction... A+B ======= C +D
maybe a bit of basic mass balance terlibat....tapi aku tak sure peringkat ape soalan nko nih..if u are in school then aku rasa tak banyak sangat pengiraan yg pelik..

di peringkat lkagi tinggi, kena balance persamaan kimia guna pH, selain daripada kaedah atom balance/mass ba;ance yg biasa....

dalam kimia fizikal jugak ade juga bab yg kena hafal such as tindakbalas certain substances dan juga warna2 sebatian oksida..i.e plumbum II oksida warna ape???

dan juga sifat2 kumpulan jadual perkalaan..kumpulan 1 sifat dia ape? dan seterusnya.......

yg ni memang kena hafal...

yg paling aku suka struktur atom....kena hafal juga setiap petala atom tu dan juga rupebentuk petala2 nih..
teori ikatan2 pon best... setipa ikatan ie, ikatan logam, van der waals, ikatan karbon mempunyai struktur dan sifat2 yg menarik utk dikaji...


aku memang minat kimia...FYI SPM Kimia A1..hehehe show off sikit....

utk berjaya, kena la hafal dan paham konsep atom dan molecul.......aku dulu hafal 20 unsur pertama jadual dan hafal la molecul2 yg penting i.e NO3- , OH- , (SO)4 2- etc..etc

lagi satu subject kimia yg best jugak = kimia analitical...yg ni more kepada analitical method utk mengenalpasti sesuatau bahan...banyak guna mesin2 canggih sperti HPLC, GC, SFC, MS etc..etc
macam CSI la..amik sampel pastu test dalam mesin...result will tell what is the composition dalam bahan tuh.....

ade la sikit2...dulu2 masa buat experiment n ade jugak helped my lecturer....

all sort of expensive analytical instruments ade kat lab tuh...

Agak2 nyer maner lagi susah ??? Kimia Organik ker Kimia Fizikal

salam..

dua dua susah...

tapi sekarang kimia organic tengah laku...sejak org jumpa conducting polymer, OLED,PLED,MOLED dan macam2 LED lagi laa..
kalau terer sintesis menatang2 nih, confirmed org cari hampa...

Pala hotak Lu,

Sorry.  DIC tu ape ye..?

pendapat saya,
kimia organik- byk sangat hafal
kimia inorganik- banyak sangat nama weird2.
kimia analisis- banyak sangat persamaan kimia
kimia fizik- dah tak ingat sangat..banyak  calculation ke?
kimia industry- paling best.. byk related dgn industry sekarang.

haku lupa habislah kimia. Tak berapa suka kimia tapi ada suka sikit2 kimia fizikal. Ada belajar subjek thermodinamik. interesting but lupa habis dan pernah dapat A+ dlm subjek tu. Kerja sekarang langsung tak ada kait mengait ngan kimia.
