NO

activation energy decrease witha catalyst not without..

yeah it decreases with catalyst so it increases when no catalyst is used

 

[Hisham Khan]

T

i did activation energy increases coz it was now done without a catalyst.. :/

EMP DOESENT CHANGE ACTIVATION ENERGY

 

[Hisham Khan]

NO

I think it was ... Wasnt Answer A

 

[SohaibButt]

I think it was ... Wasnt Answer A

No boi carbon must be bonded with 2 different atoms

 

[Hisham Khan]

No boi carbon must be bonded with 2 different atoms

Yes but it did I guess

 

[SohaibButt]

Yes but it did I guess

Nope maann it was ch3-c-ch3

 

[Hisham Khan]

Nope maann it was ch3-c-ch3

I waas going to choose B fml

 

[A*****]

I did B bcoz ethanol have ch3

Ethanol has no SECONDARY alcohol group so triiodomethane is not formed

 

[SohaibButt]

Ethanol has no SECONDARY alcohol group so triiodomethane is not formed

Yes ur right

 

[Hisham Khan]

It is true.If you pray to god by true intent ,anything can happen.I sat till 5 even after sehri ratafying and over 7 8 repeats came.

 

[Mts.99]

Ethanol has no SECONDARY alcohol group so triiodomethane is not formed

but ethanol does show positive test with iodoform

 

[SohaibButt]

but ethanol does show positive test with iodoform

No

 

[SohaibButt]

No

Yessss!!!

 

[SohaibButt]

CHI3!!

 

[Hisham Khan]

No

yes?
Ethanol is the only primary alcohol to give the triiodomethane (iodoform) reaction. If "R" is a hydrocarbon group, then you have a secondaryalcohol. Lots of secondary alcohols give thisreaction, but those that do all have a methyl group attached to the carbon with the -OH group

 

[SohaibButt]

Yeah ethanol was exceptional so it is B!

 

[Hisham Khan]

Yeah ethanol was exceptional so it is B!

lmfao I choose B by luck I guess.My mind wasnt working in paper

Litmus turn blue was ok.And hat were other points for base reaction ???
