How was paper went of CHEMISTRY 5070/22

For the physical properties of magnesium astatide i wrote

High melting point. and soluble in water. Is this correct? 2/2?
Yes correct ; it could also had been about electrical conductivity !

 

[Syed Mirak]

i wrote the same thing

For the physical properties of magnesium astatide i wrote

High melting point. and soluble in water. Is this correct? 2/2?

 

[sid2333]

no, i got it 62.9. This has been done accidentally

Even not 62.9%? What question was this?

 

[sid2333]

I also wrote 1) HIGH M.P/B.P
2) Does not conduct electricity (when solid).
Its solubility in water is also correct i guess

 

[sid2333]

As u may know poly means more than one, so many unsaturated compounds containing multiple bonds between C-C atoms. 1 mark tw mil hi jaega out of 2.

For Polyunsaturated i wrote it has double bonds in a number of places, many double bonds. Is this correct?

I was going to write about conductivity, but changed it to solubility. :/

WHAT? What did my answer lack?
I mentioned it has ''Many'' double bonds, in a NUMBER of places.
And i wrote on top ''Poly=many''..

Can be..

tw phir mil jaenge 2 marks.

 

[Dark Destination]

tw phir mil jaenge 2 marks.

Okay

Just hope i don't lose that mark in ''Sugars''.. thing..

Wikipedia says:

Sugar is the generalized name for sweet, short-chain, soluble carbohydrates, many of which are used in food. They are carbohydrates, composed of carbon, hydrogen, and oxygen.

You will get1 mark.u needed to.mention Carbon to Carbon double bonds

 

[Dark Destination]

You will get1 mark.u needed to.mention Carbon to Carbon double bonds

In the fat that was given, their were double bonds between CARBON and OXYGEN.

 

[sid2333]

but don't you think that the compound containing unsaturated compounds means it actually contains mutliple bonds b/w carbon atoms? Just asking...

There was also. Long chain molecule on the right.that contained those bonds

Has POLYUNSATURATED Come in the past papers ever? The definition?

 

[Dani 97]

I think it glucose not sugar

 

[Dark Destination]

I thought there would be one mark for

- Double bonds/Multiple bonds.
- In a number of places/ many.

2 marks.

But now you're saying we had to mention between CARBON ATOMS :/

 

[Dani 97]

Has POLYUNSATURATED Come in the past papers ever? The definition?

It has many carbon carbon double bonds.
