ones natural others synthetic

but what is the difference in STRUCTURE?

but what is the difference in STRUCTURE?

Both contain Dicarboxylic acids and Di-alcohols as monomers. I guess no change in the structure (both have ester linkage). Just that fats are natural polymers, and the other is synthetic.

can any one tell the whether displacemnt rctn r cmng

and remember for fats monomers are fatty acids and triols(diol,glycrOL) and the monomers are not continous or we would never run out of energy

but what is the difference in STRUCTURE?

Oh, in fats, the glycerol (alcohol monomer) has three OH- groups. And in alcohols in terylene, 2 OH- groups.

but what is the difference in STRUCTURE?

fats have similar linkages to that of terylene (ester linkages)
Only that their monomers consists of glycerol and fatty acids; different from terylene.
structure of fats

wats that??

metal displacement reactions

 

[bogus]

tell me something in titration i cant remember....see first we do it with indicator,then note levels..bla bla i know and discard solution. I read somewhere k if we do not want to discard solution and use it like that we remove the indicator with something. Is that sand paper???? Cant remember where i read it and what the material was please help

Those are so easy, and yes they might come.

thanks alot. i remember em. but i thought y waste time doing off topic questions

I don't remember. Plus I don't think that this method would be acceptable because in the first trial you are unsure as to what amount of acid is needed to JUST titrate the base and that's why you use the indicator. Even with indicator you, unknowingly, add slightly more amount of acid to the base, so the resulting salt will be contaminated, and the TATA salt company will never accept your salt. Even if you, somehow, remove the indicator it wouldn't help. Therefore, you have to repeat the experiment WITHOUT the indicator this time. That's what I even saw in Mark scheme.

thats charcoal. we boil the titrated solution after adding charcoal and then filter it off

but what is the difference in STRUCTURE?

the difference lies in the monomers...
for natural fats there is only one monomer with 2 diff functional groups on both sides, eg
HOOC-C2H8-OH
but for esters there are two monomers, each with a similar functional group on both ends,eg
HOOC-C2H8-COOH AND HO-CH4-OH
but in both cases the linkage remains same...

can you please elaborate how will it help. please and thankyou

 

[Rimsa]

it absorbs the indicator i guess
not sure

not sure

o i get it the carbon in charcoal absorbs the colour and taste just like carbon purifies water.
