I wrote 3 o levels cuz of chemistry and i did not make dat subject in any of it.....What do u expect...... Ogun asotele, ki pa aro #iyen aro toba gbon#

Good idea Bro.

Preciousjoz:
actually, I think it should be 1 phenyl ethanol.

Yh.. That's only if you'd call CH₃OH Ethanol, but apparently it is not.

Pes13:
Gud a.m,

Thought av studied chemistry heard enough, nt knowing I avnt read nada. where on earth are those organic compound coming frm. To tink of it, am aspiring for mbbs, I pity ma sef.

Hehe.. Lol

kumpharm:
Now you know.. The course is visible in my moniker..

Wow Pharmacy?? Congrat girl! March 21st, right?

MockinJay:
Name this one

5 Ethoxyl 2 Methoxyl Diphenol (rubbish )





But I'm sure of methoxyl and diphenol.

estijaz:
mmmmm okkk but now on now,later in d afternoon,am kinda busy ryt now

Alright then.

MockinJay:
Name this one

Hmm. I'll get back to you on that one, soon.

estijaz:
it decreases,acidity is all abt d ability of a compound to dissociate in water giving hydrogen or hydroxonium ion as itx only positive ion.u will agree wit me dat a long chain hydrocarbon can not dissociate easily wen compared to a short chain hydrocarbon.so therefore as the alkyl group of a carboxylic acid increases,itz tendency to dissociate into ions decreases and hence itx acidity decreases

Good! So right!

MockinJay:
I was gonna argue but then I saw your moniker.

True..Phenyl and Menthanol. I treated them as two different Compounds entirely. CH3 attached to benzene ring(Toluene) you are probably right.

Yeah..ElectElect

Argue?

estijaz:
yep,if u dont knw den u gotta dig deep dude

Hoho Give me an example please.

kumpharm:
Been admitted already..

Oh..(Never knew) What course?

MockinJay:
..

Compounds present are actually Phenyl (C₆H ₅) and Menthanol (CH₃OH)

It's Phenylmenthanol. Are you an aspirant?

kumpharm:
I'm good dear, Good morning

Good morning! How about your admission??

MockinJay:
1. For two reasons. First, they are both carrying the same mole. So one could easily cancel them out. But why? Cause it's easier and faster.(reason 2)

2. I made use of it. Since it's 1,it won't show just like HCl is also 1HCl. Now, if I were to use the 2mole instead of the 1mole. The molar masses of Na and NaOH would be 46 and 80g/mol respectively.

3. The "I don't have a calculator but want to be fast" formula

Whether I use the 1:1 mole ratio or 2:2 mole ratio, I would still get the same answer.

2Na : 2NaOH
2* 23 : 2* 40
46 : 80
2.3 : x

X= 80 * 2.3/46
X= 4g

Got it! Thanks

Who can name the above

Could you answer that?

Meanwhile, more calculations coming up. @Holamarncy, MockinJay and DrHost.

Holamarncy:
dat z method z tym consuming
since dey av d same mole
23 = 40
2.3 = X
of course its jxt 4

Yours is faster but not comprehensive.

Kumpharm.. What's up nw?

MockinJay:
4g.

The only elements/compounds to include is Na and NaOH. Since they both have the same mole(2). Cancel out so it'd be 1.

Na : NaOH
1 : 1
(mole)


23 : 40
(molar mass)


2.3 : xg
(mass)


X= 40 * 2.3/ 23
X= 4g

NaOH= 4g when Na is 2.3g

Please if I may ask:

1. Why not use 2:2 mole ratio instead of 1:1?

2. I noticed you didn't use the mole ratio in the calculation, then why should we be concerned with the mole ratio in the first place?

3. Could you tell me the exact formular you used for the calculation?

DrHost:
yes it decreases there is supply of excess electron..... The larger d r d less acidic...... Ur calc use 2 mol of na= 2 mole of naoh 0.1 mol =x o.1 is get by dividing 2.3 with 23 cross multiply that gives 0.1 multiply that naoh mm and u have ur ans 4...... U can also solv with mm directly.... Organic get calcs ooo

Where did you get 0.1 mol from

Holamarncy:
e suppose decrease i guess

Correct! Good morning bro

Before going to bed lemme put this down (hoping to see an answer tomorrow)

Complete this:
Under the general properties of carboxylic acids, as the number of carbon atoms in the alkyl group increases, the acidic nature ______

Holamarncy:
may God help me ha...i never reAd physics nd biology..23 days sounds close ..bh 3weeks sounds a bit far.....

Me never touch English at all.. Not even Forcados (abi wetin dem dey call ham )

cassyrooy:
Everyones reading?
Gonna sue me?

Well he's got no right to tell me of the thread to romance etc. But it doesn't make me more serious than any other UI aspirant.

What course are you going for again?

estijaz:
u can't possibly b serious n dis is not organic chem na

Does Organic Chemistry have calculations too??

cassyrooy:
Hi, did i hound you?

Na. Just be careful with the way you play with tin cans (everyone is reading)

cassyrooy:
*starts eating my books, cos i'm running out of time. When it digest, the nutrient will go to my brain before jambs exam day*

In GEJs' voice "Tamunor!"

I used to think he was Igbo.

estijaz:
Nope not atall but I think my ancestors used it,lol,of course,who hasn't

d textbook is gud anyway but itx not dat explanatory datx y u r still avin issues wit it.If I recommend d textbook I used for u,u myt not c it in d book shops and libraries around u

d only tin I can actually offer u now is my help in any area u find confusing,we will work together to increase ur strength in dem#hope u dont av difficulty wit d calculations sha#

A lot of difficulties. Imagine me looking like a fish that has be deprived of water for six days when I read this:

2Na + 2H ₂ O ---> 2NaOH + H ₂


From the above equation, calculate the mass of sodium hydroxide produced by 2.3g of sodium.

A. 0.40g B. 0.80g C. 4.00g D. 8.00g

[H = 1, O = 16, Na = 23]

cassyrooy:
23? Jesos?

Yes o. That's actually 3 weeks and two days

cassyrooy:
Be like say u no like the head wey u carry, u need bottle for am.

BTW why associate me with romance when i need education to secure my future? Don't try that again

This cassyrooy sef

Who can name the above

estijaz:
lol,wat textbook r u using to study organic chem?

Ever heard of New School Chemistry?

How far na... Biggest boss Fembleez1



I dey hail oo

DrHost:
let me say I didnt see this....., proton I think organic become more interesting when u knw d functional groups and their features

Yh. That helps to identify them easily and also know their chemical properties.
