HOW WAS CHEMISTRY PAPER 22 ?

[Idolfanatic95]

What was the Answer of question 5 ? the 2 isomers ? I had a cis-trans and an optical isomer pair are these correct?

Yes

I stared at that compound for 5 minutes. It was CHO, everybody's accepting that there was an HO in the end. That's got to be an aldehyde.

anyway, whatever it is, its worth one mark!

It it was (CH3)2CHO, then the last carbon has only three bonds attached if u consider it to be an alcohol . Secondly, structural formula always matters. If u show me any compound from anywhere which is an alcohol and has a CHO in the end, I'll accept that I'm wrong then.

Sorry its (CH3)3CHO,i wrote that by mistake and i did correct it

it was an alcohol dude tertiary one

See, as I said it before if there's a hydrogen between a C and an O, that's impossible for an alcohol. And it was important as then you had to mention the colour changes in the table

you know what if this can relieve you then yes you are right, we are wrong!

It was (CH3)3CHO, There is no way it can be an aldehyde, that way carbon's gonna make weird 5 bonds dude The only color change was for the compound B

exactly! and there are 7 points allocated on the 1st table and 3 on the 2nd table (one for identifying B, one for initial colour and the last point for the change in colour)!

dont get me wrong but your organic seems a bit weak,i used to make such silly mistakes too
Sometimes we do get fooled by such situations

Ansar this was the structure look

Okay bro. It was an alcohol with a hydrogen having a bond with C, as well as oxygen. Maybe our chemistry books need a change now as we have new philosophers here.

^Yep yep

lol! what does philosophy have to do with chemistry?! in anyway, its only worth one mark!

We are here telling you what the fact was, certainly not accepting any sarcasm. Thank you, take care!

 

[speedy20]

Dude you are wrong accept that

 

[Nishii]

frankly, you are being freaked out for only one mark ==

 

[speedy20]

And now can please tell me that what were the two pair isomers ? I had a cis-trans pair and an optical isomers pair am i right?

 

[Ansar Khan]

exactly! and there are 7 points allocated on the 1st table and 3 on the 2nd table (one for identifying B, one for initial colour and the last point for the change in colour)!

Were they seven or 6? And please, CIE examiners that not that lenient that they'll give u straight marks for just writing a letter and a color change.
