oh...then i really wants to know that answer....yesterday the chemistry test...i wonder u still remember the questions asking the test for the pentanal and but-1-ol question.about wat test can differentiate the pentanal from but-1-ol. iirc,it shud be that 2 organic compound with that name.it's above the question asking abt carboxylic acid reacts with na metal. then u know whether it is correct or not if i write I2 and naoh(aq)??wat asnwer did u write???

wah, i got RM500 offer for my laptop, deal or no deal?

iodine ca .. but need to change ur secondary alchohol 1st if not mistaken !!
you guy really is form 6 student ??
pentanol and butan-1-ol different in secondary and primary !!
if changing to charboxylic acid then need use the strong one to makign further oxtdation in order to reasult in co2 release from the secondary alcohol ...
correct me if I'm wrong ... Those chemistry ald 3.5 years ago >.<

wow u really remember all these things.

maybe i learnt them all during matric, 5 month learning a year STPM subject, so that's why i cant remember it well

oh..it's pentanAL...not OL....so how??but triiodo form test is A2 syllabus...i scare the AS exam dun allow us to use A2 study de thing....haizz...did u put 2,4-DNPH for that fantasia??haizz..

no la ...
this consider forget alot ald ..
if not i can answer they question and give the correct answer !! ^^

i actually also want to confirm the name of the alcohol and ketone with fantasia only..if the name really is pentanal and X-1-ol....then can lw....cuz any alcohol with the -oh group at carbon no.1 will give negative results with the iodine and naoh(aq) except for methanol la. so i want to confirm what is the ketone.....

Ops ... that alcohol is primary >.<
My mind had problem ald !!
you are right ... may i know which course are you guy taking ??

A level....sienz...
