Thank GOD!!

tuka for that hcl and sodium nitrate

You forgot the 2 electrons in the inner shells as well
You only counted the outer shells of electrons

You would have counted the outer shell electrons too.
But once you encountered an mcq, where you thought the marking scheme was wrong, but then i told you that you hadn't counted the inner electrons.
So you applied that concept here.

Organic compounds. Wo to saaray hi organic hain. Lipids bhi organic. Hydrocarbons. Ethane. Blah blah.

Yes and glucose falls under it
Just like alkanes and alkenes
They are different but still fall under hydrocarbons

oh teri khair ,How was A1?meri tu phat gai thi the rest was fine and interesting thing was Section B was ''HALWA''

Well that is wrong.I wrote monosaccharides about that class q.

Can you please reply properly?

I did.

I also wrote 22.
Muhammad ali got it wrong

And there was an MCQ about which bulb will light?

 

[potterfan97]

I think the class of compound was alcohol because monomer is diol in carbohydrate

 

[Abdullah Zahid]

it was glucose as glucose is the monomer used to make carbohydrates

I am saying that once there was another mcq like this, and you posted on this thread.
You thought the marking scheme was wrong. Where you were saying B is the answer which was 4. But the marking scheme said it was 10.

The same type of mcq came again.
And now you knew that you had to count the inner electrons. (Y)

Not always. There is Fructose. Sucrose. Many of them.
I wrote ''Sugar''

 

[Abdullah Zahid]

cheeni?

 

[Abdullah Zahid]

what was mcq 17? That energy fuel one

 

[Awesome12]

The one that contained H2so4...it was easy.

There was no electricity provided like in electrolysis

 

[DaniyalK]

How many alcohols were there in the MCQ?

 

[Awesome12]

Ammonia Conc was 2.07,In Sec B it was lithium and the metal flowchart was iron,hydrogen,iron(II) chloride,Iron (II) hydroxide and then Iron (III) chloride and hydroxide....

Dil kush kardia

 

[DaniyalK]

There was no electricity provided like in electrolysis

Electricity will be generated because of the different reactivity of metals.

 

[Awesome12]

Electrons automatically move due to change in reactivity,dont you know?It was Ag and Cu,electrons would flow between them....

No what I mean is there was also Zinc and silver in option B

 

[DaniyalK]

About that electrons one? Did we have to count inner shell electrons? Coz I was pretty sure I read all electrons and so did 22. But all my friends said outer shell electrons - which were 8.

And was that H2S04 one correct? I think it had Ag and CU - both below H.

You had to count the inner ones too because 'all' was written in bold. And it doesn't matter if they were below H.

 

[DaniyalK]

No what I mean is there was also Zinc and silver in option B

Was option B the one with NaCl electrolyte?Because that was solid.
