What about the halogen question where it asked about the trend in volatility of group 7 was the answer permanent dipole interactions increases?
For group 2 trend it was solubility of sulfates decreases.

yesss I chosed sulfatesss

 

[Hisham Khan]

i

i think it was induced dipoles not permanent

permenant in halogen compounds and vanderwall or iduced in only halogens

 

[Hisham Khan]

NO + 0.5O2= NO2

lmao I am lucky!

 

[Kanekii]

i

permenant in halogen compounds and vanderwall or iduced in only halogens

So it is induced or permanent?

 

[Kanekii]

Sulfur has 2 unpaired

Yes i understand i simply misunderstood the question

 

[Hisham Khan]

So it is induced or permanent?

For the question that came volatility decrease because bond energy increases.Repeat question.vanderwall increase as number of electron increase

 

[Kanekii]

I know this but what i didnt know was the other name of van der waal forces.

There isin't any 'other' vanderwall forces.There is only one vanderwall force. permenant dipole is not type of vanderwall.other one iss hydrogen

I mean induced dipole/london dispersion forces

Bond energy DECREASES down the group

 

[Hisham Khan]

Bond energy DECREASES down the group

yes bond lenght increase bond energy decreasee but option was something related to vandewall forces right.do you rememmber the exact correct answer

 

[A*****]

Yeah it was that temporary dipole induced dipole forces increase down the group something like that

 

[Hisham Khan]

Yeah it was that temporary dipole induced dipole forces increase down the group something like that

yeah i choosed that

Which page was this on??

 

[Hisham Khan]

Which page was this on??

We don't have that much of a great memory lmao

Which page was this on??

That is pretty obvious...non polar molecules only have vander waal's forces bw the molecules which are broken during melting/boiling

The brown gas is for nitrates but it was sulfates so only litmus turns blue and white soilid right?

Yes

 

[SohaibButt]

Yes

What was the answer of combustion reaction in which volume of co2 given n mass of hydrocarbon compound

 

[zap-cannon]

What was the answer of combustion reaction in which volume of co2 given n mass of hydrocarbon compound

the empirical formula one? CH2O
does anyone of you remember the question where we had to say which molecules showed cis trans isomerism ( section B ) . what did you guys get
