how was chemistry paper 22

[s_hithappens]

I think i wrote Si for that is it write?

sicl4 reacts with water

 

[shah zaib]

what was the question exactly?what 'covalent' chloride dissolves in water and conducts electricity?? i have a feeling they didnt say covalent CIE wouldnt ask such a complicated question for 1 mark.

haha...but the question indeed was to name a COVALENT chloride which conducts when in solution.

I clearly remember them asking for a covalent chloride

uff buddy let me have some hope .....and how come everyone saw the covalent part except me

eyes and brain jkng man i made even bigger mistakes in phy chill

 

[stella jazz]

i wrote IClhas the strongest dipole as the difference between the electronegativity of chlorine and iodine is the greatest
is that right?

i wrote the same thing

Dude would you stop stressing over it? focus on the coming computer paper dude!

Let's all chill together got some cold drinks and ice creams ?

 

[Jinkglex]

SiCl4 does not conduct.

wht abt the grade trashold for this paper..?

 

[haha101]

people white is a colour . colourless is not a colour . understand the difference

is it okay to draw the structures by pencil ?

I drew them in pencils too. You're actually supposed to make any diagrams/graphs in pencil

 

[Beaconite007]

what did u write for covalent chloride ?
i wrote Phosphorous //

but i think it wud have be Beriliyum chloride , which is covalent , dissolves in water , and also forms conducting solution

I wrote Al.

thanks man . My heart was in my throat when someone told me you had to draw em in pen

around 45 (its just a guess) !

wht abt the grade trashold for this paper..?

K floats on water , doesn't sink ! and C i dont think it actually does form a pi bond :/ isnt it single bonded ?

Only Group IV elements like C which has 4 valence electrons can form pi bond through sp3 hybridization.

i hope for phosphprus too xD XD

dude y take risk with carbon when you know oxygen has a double bond -_-
