@Abcd 4C-H,3Cl,1Pt-C

But I am not sure as I am yet to learn these things

@Jasmine But I don't understand how that bond between alkene and metal is not sigma

@Jasmine Isn't your phase test on Saturday too?

@Jasmine This is the most AWFUL part of fiitjee. Not completing the syllabus and conducting phase tests.

What would be the IUPAC name?

@Abcd

Are you giving JEE too ?

@EshaManideep yup everyone's giving Jasmine AK Ice

Do you people give any mock JEE exam online regularly?

How do you do this?

This is from Himanshu pandey

And I have solutions app but they haven't givensolution for specific problems

My MSC will be arriving day after tomorrow

Is it easier than the stuff I asked above

Hmm

1 sec

In first one, which Hydrogen will be lost? From sp3 carbon or sp2 carbon?

α hydrogen is Hydrogen attached to the carbon attached to ketone group right?

Aren't there 2 of them

One towards left other towards right of tthe ketone group

Damn, I'm confused

@Abcd our portion is very incomplete but what can we do...

@Abcd what is the answer? The back bonds have π bond character

@IceInkberry yes.. these days i use allen package

@Jasmine What is the hybridisation and geometry of $\ce{[Cu(NH3)4]^{2+}}$

@Jasmine same lots of stuff is left .... :(

@Abcd hybridization of Cu

@Jasmine yup

@IceInkberry I thought so, but then I thought carbon with more S character is more electronegative and hence has most acidic Hydrogen :/

@Jasmine ???

@Abcd is it dsp2

@Jasmine HOW??

@Abcd is it dsp2 correct?

@Jasmine YES

Cu+2 you can draw

@Jasmine I know it has $3d^9$

Then what??

I feel it should be sp3

Because no d orbital is vacant!

@Abcd no

Cu is exception

Cu+2

@Jasmine ??????????/

@Jasmine ????????? What exception???

@Jasmine NO

I did not mean that

Its 3d9

:47228237 Do you know what Cu is? It is 4s^2 3d^10

@Jasmine Yes, then???

@Abcd give me some time i will upload a pic as i cant explain this way

@Jasmine How much time you need?I am very worried.

@Abcd

@Jasmine I have never seen electron being transferred from d to 4p

@Abcd but pairing is important..

You want in s?

Then how will Nh3 donate lone pair of electrons

@Jasmine ??????

@Jasmine why cant it be sp3???

@Abcd i dont understand how you are saying sp3

@Jasmine pairing happens among the d orbitals

@Abcd how can 9 electrons be paired

@Jasmine dude 1 electron can stay unpaired. It happens many times.

@Abcd in presence of a strong field ligand!!

@Jasmine !!!???

@Jasmine after moving your electron to s you are not getting a pair

@Abcd i am not moving it to s

@Jasmine so???

@Abcd quora.com/What-is-the-hybridization-of-Cu-NH3-4-2+

Your exact question

@Jasmine what gibberish has the answerer written? "Because NH3 is a VIP..."- rubbish.

@Abcd even i dont know what VIP

@AvnishKabaj do you think the hybridisation of Cu in [Cu(Nh4)]+2 should be sp^3 ?

@AvnishKabaj $\ce{[Cu(NH3)_4]^2+}$, what is the hybridisation?

@Jasmine mistyped.

@AvnishKabaj please enlighten us phase test is close

How do I do this question? The answers dont' seem to make sense- for instance in a) I feel e- density order should be II > I since methyl group is e- donating. I'm really sorry the picture is inverted, in my computer it is the right way around but it gets inverted when I send it.

@Jasmine @Abcd

Dunno guys

Sp3 according to me

@IceInkberry the hecks tgar

@IceInkberry ohhhh ok

@IceInkberry typo for "that"

@IceInkberry that's just English yo

Don't do drugs kids

@AvnishKabaj

@Hema 's question doesn't tally with what was written here quora.com/Why-does-NR3+-have-a-greater-I-effect-than-the-NH3+

@Hema This one

@IceInkberry ????

@AvnishKabaj @Jasmine ^^??

@IceInkberry why cant he speak directly. I hate these self proclaimed smart, trying to sound cool quorans.

@IceInkberry Giving pre AITS mock tomorrow? @Jasmine @AvnishKabaj On Mypat??

@IceInkberry Did you get any nice link for the rank vs marks thingy?

@Abcd no

@AvnishKabaj what's the answer to EAN question

@Abcd + $\infty$

@Abcd dunno

@Abcd a?

@AvnishKabaj wrong

@IceInkberry what do you mean!?

@IceInkberry ya, even I got fed up of reading "AITS doesn't decide your JEE rank", "Dont get demotivated", "Its very hard" etc on the internet everywhere!

@IceInkberry mains rankss and marksss'????

@IceInkberry I dont understand what you mean by "why sidwick's theory."

@IceInkberry i was solving a book it had around 10 questions on Sidwick's theory. Quite nice.

@IceInkberry no girl you have a misconception.

@IceInkberry oho its such an easy theory. why you worrying about it

@IceInkberry BTW cyclopetnadienyl is a commmmmon ligand

@IceInkberry No it donates 6 electrons

@IceInkberry maybe coz its not done in your coaching

@IceInkberry I know JD lee doesnt have it IIRC

or its in the last pages of JD lee

@IceInkberry not given there too IIRC

@IceInkberry what rank does a score of 150 yield?

@IceInkberry teacher

@IceInkberry if you want my notes Ill send but I doubt youll understand it

@IceInkberry Sir said that they have pulled down the level of AITS from last year ...

@IceInkberry if your allen modules are good it will be given there....

@IceInkberry how was it?

@IceInkberry similar to regular allen tests?

@IceInkberry oh that means you are going to rock it.
