chem online xD
ever hear of studying online? well my chem sucks. like seriously. -.-
so today, b4 exam. ryll is helping me study CARBON COMPOUND ONLINE. =)
which is actually quite weird but at least it works. ;D btr than me nt studying at all.
THANKS ryll! i had to catat it down in my blog so i'll always rmb youuu! kekeke.
[ *c h e r y l l* ] ('.') says:
*lol
*anyyyywayyyyss
*alkanes
c a r y n ♣ says:
*ok..
[ *c h e r y l l* ] ('.') says:
*they are SATURATED
*hydrocarbons
*hydrocarbons means..organic compounds that only contain carbon and hydrogen elements
*hence the name
c a r y n ♣ says:
*ok..
[ *c h e r y l l* ] ('.') says:
*the molecular formula is CnH(2n+2)
*like normal math ni
*xD
*alkanes oni ada SINGLE bond
c a r y n ♣ says:
*uh huh.. means oni gt -
*no =
[ *c h e r y l l* ] ('.') says:
*yeaa
*then naming u noe right
*first 4, MEPB
*then the rest all same ni
*xD
c a r y n ♣ says:
*yea
[ *c h e r y l l* ] ('.') says:
*physical properties
*em..
c a r y n ♣ says:
*wait
*i tak faham CnH(2n+2)
*apa itu?
[ *c h e r y l l* ] ('.') says:
*em..
*lets say 1 carbon atom
*which is methane
*means the n = 1
*so.. the methane formula is C(1)H(2(1)+2)
*so.. CH4
*methane
c a r y n ♣ says:
*ohhh
*ok ok
[ *c h e r y l l* ] ('.') says:
*ethane is?
c a r y n ♣ says:
*so mu rmb le hor?
*C(2)H(2(2)+(2)
[ *c h e r y l l* ] ('.') says:
*erm.. i guess... :S
*i hope the ygive the formula thingy la
c a r y n ♣ says:
*c2H6
*??
*is it?
[ *c h e r y l l* ] ('.') says:
*yeap
*:D
c a r y n ♣ says:
*okay ;D
*nex nex?
[ *c h e r y l l* ] ('.') says:
*physical properties
*as the number of carbon atoms increase, the size of molecules increase
*they are NOT SOLUBLE in water
*they are SOLUBLE in organic solvents
*they DONT conduct electricity cuz consist of molecules oni; no moving ions
c a r y n ♣ says:
*alkane. carbon atom uop. size uo. nt soluble in water. soluble in organic solvents no conduct electricity
*ok
[ *c h e r y l l* ] ('.') says:
*em..then.. its like..MEPB are gases
*the rest liquid
c a r y n ♣ says:
*oh ok..
*OMG i juz went down to get water
*tv was on. clash of the god. its like. discovery abt all greek legends!!!!
*damn exam!
[ *c h e r y l l* ] ('.') says:
*LOL
*dont worry
*got repeat
*:D
c a r y n ♣ says:
*but i wont know whennn!
[ *c h e r y l l* ] ('.') says:
*haha check
c a r y n ♣ says:
*i duno whr the thing is. lol
*my hse oway duno go whr one the mag
[ *c h e r y l l* ] ('.') says:
*guide guide
*the..
*menu wan
*but susah abit lar
*lol
c a r y n ♣ says:
*yea
*haihh.. sudah ditakdirkan
*nvm study study
*=(
[ *c h e r y l l* ] ('.') says:
*lolXD
*chemical properties
c a r y n ♣ says:
*k
*u gone?
*o.o
[ *c h e r y l l* ] ('.') says:
*huh?
*oh i waiting for u torespong
*respond*
*lolXD
*okeh okeh
*i go on
*haha
c a r y n ♣ says:
*LOL i oso waiting
[ *c h e r y l l* ] ('.') says:
*uhh
c a r y n ♣ says:
*k..
[ *c h e r y l l* ] ('.') says:
*then alkanes undergo SUBSTITUITION reaction
*with uh.. halogens
*halogens are like.. chlorine n bromine
*under ultraviolet light right, alkane and chlorine undergo substituition..
*say..
*methane + chlorine ----> chloromethane
c a r y n ♣ says:
*ooohhh
*cool
*ok..
*thn?
blablabla~ it went on for a while...
if i can answer tmr. its tanks to you! CHERYLL!
TQ. ;D
