what is the difference between saturated/unsaturade carbo...among other Q
« on: December 28, 2005, 02:03:47 PM »
what is the different between saturated and unsaturated carbohydrates?

how is the combustion rate of a polymer decreased by radical scavenging? radical recombination?

radical scavenging:
H* + HBr ---> H2 + Br*
HO* + HBr ---> H2O + Br*

radical recombination:
HO* + Na* ---> NaOH
NaOH + H* ---> H2O + Na*
HO* + H* --catalyst--> H2O

that is the process as explained in the book i just do not understand what is happening....

what is an ester, and a carboxilic acid? what is their difference?

these are all the questions i have to this moment.... :Confuzzled:

Here is an example of an unsatured carbohydrate. However, they are extremely uncommon.

difference between carboxilic acid and ester
« Reply #3 on: December 29, 2005, 04:50:40 PM »
carboxilic acid is that formed from the oxidation of : primary,secondary acohols, aldehyde or ketones  with KMNo4 it is of formula CnH2nO2

ester is the result of reacyion between a carboxilic acid and an alcohol where  water is released:
 carboxilic acid + alcohol --> ester + water
