What is the number of isomers of C2H2Cl2 including cis-trans isomers?
A= 2 B= 3 C =4 D= 5 how is the answer B can anyone draw the structures and explain? PLZ?

There you go the 3 types of isomers that can be formed

 

[The Chill Master]

how is the answer B?

Because B is an aldehyde
A is an Alkene i think
C & D are ketones

how does Nitrogen have only 1 lone pair? :/

 

[Mimick]

How did you got 17?
Explanation please

Ok wait

 

[princess Anu]

how do we know which chloride reacts and which dissolves? :/ and ii why can't it be redox

Look... There are total 7 electrons in the other shell...so it donates two pairs of electrons to sulfur present on both the sides... Remaining are 3 .. Lone pair means it should be 2 electrons, right? So therefore now ONE lone pair is present...althoug there's one more electron left...I hope I found some sense..

 

[Mimick]

but an aldehydes means carbon aTom attached directly to functional group and and an h .Though I am not sure

Let me confirm..

I think you meant 5 outer electrons, and it donates 1 each to the sulfur on both sides. Leaving 3 left.

Perhaps you should try to draw all the bonds out, especially on the CHO to convince yourself its an aldehyde functional group.

Oh so we do it this way Thanks a lot

Oh yeah I get it thanks a lot.

Well our teacher gave us the table showing which Chlorides reacts and which dissolves
All Basic compounds dissolved in waters forming free ions in this case Na+ & Cl-
While all others dissolves
And the last question I dunno sorry.

 

[princess Anu]

that means all basic compounds will dissolve while others will react right?

What is the difference between Structural/ displayed/ skeletal formula for a Cyclic compound such as benzene?

Yep

can somebody solve thissView attachment 51422

somebody please explain why do we have to multiply moles of H2 by 2? I have my mock tomorrow
