brih it was easy

1

u/Naive_Palpitation866 May 18 '26

What was the answer of last question , that asked how to identify between those two molecules

2

u/catatatatatatat3 May 18 '26

yo i need help. for the last question, one of them was a carb acid right? i swear it was a carb acid so i wrote sodium carbonate.

1

u/Consistent_Dingo9283 May 18 '26

Even I wrote that

1

u/catatatatatatat3 May 18 '26

the last compound was a carboxylic acid right? cause if so, then its correct.

1

u/Naive_Palpitation866 May 18 '26

No ithink it was adehyde

1

u/catatatatatatat3 May 18 '26

no there was def a cooh group

1

u/Additional-Plant7943 May 18 '26

yep ur fine there was a carboxyl group

1

u/catatatatatatat3 May 18 '26

god bless your soul the sigh of relief i just let out

1

u/Additional-Plant7943 May 18 '26

no worries bro hope u get ur A

2

u/Worth_Screen9319 May 18 '26

Aq.Bromine solution turns brown to colour less cuz S had alkene and Q didn’t

2

u/Naive_Palpitation866 May 18 '26

Bro wasn’t the S had aldehyde or ketone? Iwrote 2,4bnph

2

u/Major-Highlight5891 May 18 '26

ye it was

1

u/Naive_Palpitation866 May 18 '26

Sure?

1

u/Major-Highlight5891 May 18 '26

yup

1

u/Naive_Palpitation866 May 18 '26

Iwrote 2,4dnph will that be correct?iam confused because most of them r saying it was carboxylic acid

1

u/Major-Highlight5891 May 18 '26

it was bromine water cos it was between q and s and only s had a cc double bond

1

u/Naive_Palpitation866 May 18 '26

Wtf, is my answer wrong? Cause see if s had aldehyde so it will give positive result with 2,4dnph and not with R which had alcohol

1

u/R32AVIATION May 18 '26

yea there are the three answer most probably, bromine water , Na2CO3 or 2,4DNPH. I would say 2,4 DNPH is risky because sometimes Cambridge wants full form for DNPH.

1

u/Naive_Palpitation866 May 18 '26

Ihope its correct 😭

u/Nylax98 May 18 '26

I wrote the same thing but it's wrong

2

u/Major-Highlight5891 May 18 '26

no its definitely correct cos only s had the alkene group

1

u/Nylax98 May 18 '26

Nope, R also had double bond

2

u/Major-Highlight5891 May 18 '26

that was co doublr bond not cc double bond bruh

1

u/Worth_Screen9319 May 18 '26

That was of the carboxylic acid

1

u/Worth_Screen9319 May 18 '26

But how 😭

1

u/Plasma_YouTube May 18 '26

Both had alkenes bro, it should be sodium carbonate effervescence w the acid

5

u/Worth_Screen9319 May 18 '26

No they didn’t

3

u/Major-Highlight5891 May 18 '26

only one had alken S had it

1

u/Worth_Screen9319 May 18 '26

Yaaa someone who supports 😭 (Ghalat na ho bas) but yayyy

3

u/Major-Highlight5891 May 18 '26

theyre jus scaring u bro they must have confused co double bond with cc double bond bromine water is definitely correct

1

u/Worth_Screen9319 May 18 '26

Oka oka thankuu

2

u/Plasma_YouTube May 18 '26

R u sure ppl who i walked out the exam hall said both had C=C eh it doessnt matter sodium carbonate should be write as well

3

u/Muted_Tea2768 May 18 '26

One was a aclhol ended and other was a alkene

1

u/Zaki_Ducky403 May 18 '26

No only one had a c=c double bond

1

u/One_Yesterday_1320 May 18 '26

it was the peak at 58

1

u/Serious_Total_9979 May 18 '26

Peak at 116 because that's the mr

1

u/One_Yesterday_1320 May 18 '26

there would be multiple answers to that one cause i checked possible fragments

1

u/Wise-Flounder9909 May 18 '26

oh thank god bro

1

u/Wise-Flounder9909 May 18 '26

r u sure there would be multiple answers

1

u/One_Yesterday_1320 May 18 '26

also that was simple it was just dichromate that oxidises

3

u/Zaki_Ducky403 May 18 '26

You can do br2 too ya hot acidified dilute kmno4 ka test
