yes of course it is

No i think oxidant is the substance that get oxidized......r u sure about ur statement?

 

[haha101]

no oxidants are oxidising agents !!! Seriously

 

[syed1995]

no oxidants are oxidising agents !!! Seriously

If Oxidants are Compounds which Oxidize Other compounds then yes.

I think its decreased ! Correct me if wrong

If the volume is increased, concentration must decrease and therefore rate will decrease.
I guess

Thankyou both

 

[Spidey21]

Thankyou both

volume and concentration are inversely proportional!!

can someone please post all the names of indicators and their colour changes ??

STATE WHY THIS CAN NOT GIVE A CARBOXYLIC ACID IN PRODUCT WHILE OTHER ISOMER OF IT CAN GIVE IT ..!!?? AND WHAT ITS NAME MEANS PROPANOL-2-OL ..!!!

i think it can. dunt know...
the name means that the OH group is linked to the second carbon

 

[asd]

The OH should be on the side of the structure i guess.

alcohol's functional group is OH not O-H , there is no bond between O and H , thats whats wrong

THNX FOR THE NAME
BUT IN PASTPAER ATP A QUESTION CAME

Q) a student found that different alcohol,altough having the same formula did not give a carboxylic acid as the product,suggest the name and structure of this alcohol

name.....................................


structure __________________________

so i posted its answer asking its reasons ..!! pls confirm me soon

 

[khizer shahab]

absolutely not ..the question said that its an ISOMER so how it can be wrong OH or O-H means same

Alcohols with -CH2-OH can only be converted to carboxylic acids !!

Year please !

dats what the difference in isomers but why cant it can produce carboxylic ????????????????/ thats the real confusion !!!!!!!!!!

That's the same thing

 

[khizer shahab]

Year please !

SURE =) W-2006-QUESTION 3 PART D

 

[asd]

dats what the difference in isomers but why cant it can produce carboxylic ????????????????/ thats the real confusion !!!!!!!!!!

That's my answer lol, in this isomer, OH is in the middle, so maybe its more stable like this. Besides, the carboxyl group is always on the end of the structure so it can not be oxidised! MY GUESS.

isomer will change the chemical properties so i guess thts why it wudnt react
