[allstarr69]

. Classify the species NH3 as an electrophile, nucleophile, or neither by typing in the appropriate word.
Use all lower case letters when entering your answer.

I neeeeed to get this right. Ive already got like 4 wrong :s. Its the pre lab work and its the last question. whats the answers?

Cheers

you have to think is it electron deficient or an electron rich compound?

i think it is neither but don't quote me on it..

 

[allstarr69]

hmmmm ill wait for a definite answer... got too many wrong so far hehe and a friend reckons its nucleo.. but then again he waz wrong about the last question...

 

[nit]

ammonia's nucleophilic because of the lone pair of electrons on the nitrogen. Same reason why water is nucleophilic.

 

[allstarr69]

thanks champ@@@!!!!

 

[allstarr69]

OMG i wrote nucleophilic instead of nucleophile!!!

BOOO!
damn 2/ 7 this is really woeful...

Do pre lab marks count at all?
Pls say no....

as far as i know, the mark you getdoesn't count, its just a participation mark.

 

[allstarr69]

oh gd gd gd
i hope your right
but then again 2/7 isnt even really participation is it hehehe

 

[tennille]

As long as you get above 20% for your marks, it doesn't matter. So you're fine.

 

[xiao1985]

2/7 and u are still fine?! lol kz kz... cuzthey want to prevent pplz just guessing... so long as u actaully did it, u can get way above 20% ...

great work nit... =)

 

[nit]

hey xiao...how's semester 2 been treating you?

 

[xiao1985]

long as u do ur prework it'd be fine... unless u r a chem perfectionist like nit, 1 or 2 errors are expected...

@nit: alright... =p though doing 3 hr math from 8 am straight isn't really the best way to start a day... usually =S

 

[Jase]

what. half the people i know didn't even know pre-work existed last sem. they scraped distinctions in the end.

 

[tennille]

The pre-work is only worth about 4%.

:NH3 has 2 lil electrons. so nucleophile

[exactly 1 month late]

 

[nit]

so late, that it's already been answered

Technically, NH3 has more than 2 electrons

 

[Templar]

So glad we do not have prework.

What did the normal/advanced people do in their prac last week?

 

[Jase]

last week?

we did acid-base titrations.

 

[nit]

lol how many acid-base titrations do you guys do anyhow? You must have done it in 1st semester as well right?
