crypsAnity:
@ Clem.. your friend was right .. it is because it has one OH group .. and amino acids are different .. they do not have only an OH group..
they have COOH .. which is the functional group for carboxylic acids.. but thats not the case anywyas they polymerise because they have two different functional groups placed end to end on their molecule ..  so u have to visualize .. u see.. they form a polymer each and evrytime
by adding on to the different group endings .. sorta like laterally inverting evrytime ..

so basically ..yeah ethane, 1,2 diol can polymerise because it has two functional group at both the endings.. whereas butan-1-ol .. just has one.. so it cant link up continuously..

IGSTUDENT:
CAN SOMEONE HELP..

I NEED SYMBOL EQUATION FOR REACTION BETWEEN ETHANOIC ACID AND SODIUM HYDROXIDE?
NOVEMBER 2005 ...IS IT A REVERSIBLE REACTION?

Shogun:
it would have same effect of normal acid. so it would be a netralisation reaction giving sodium ethanoate and water

ch3cooh + NaOH ---> Ch3COONa + H2O

and no its not reversible..

Shogun:
ok, i have a question, see:
1) how can i show in caculation tht a substance is in excess?
2)why to make alloys with metal is better than making with non metals?
3)y do sientist believe tht no undiscovered eliment is missing from the periodic table?

and By the way Thanks emi..

sweetie:
fear_fear da formula u used is rong da rite one is < mass/relative molecular mass>
and in <cl2>  der is only one mole of chlorine

hope i helped
All the best
