13wat do u mean by both r wrong
:CCl2 is less nucleophilic than :CH2 Is the statement correct

1well i read some very gud views above but
carbenes are neutral eleltrophiles so they hav same nucleophilic caracter
but i feel that i m seriously rong somewhere [7][7]
1arey i din tell it five times....
i clicked it 5 times..
server is down today at kgp...
dats y...
11wat is logic of saying it 5 times
r u a muslim lke
kabool hai
kabool hai
kabool hai
11do u have some source or r just sharing ur views (and making us doubtful)
please do tell us to which u r sure off
1It means that according to the ans both have same nucleophilic strength
11Cl to bahut bada hai aur kuch steric hindrance pose karega attack main so i go with
:CH2
1in the ans both the ans i.e. which one is a better nuceophile are marked wrong but i feel as Richa said Back bonding will be there and More over Cl is strongly electronegative it will decrese the intensity if eletrons on C therefore weakening the nucleophilic strength
1in ccl2 the cl donates its lone pair to c empty orbital thus enriching it .it s very significant in 2 n 3 period elements . by the way wat s the ans of this q
11could u please tell us something about that so that we may also know about it
1i m sure backbonding ccl2 me hoti hai inorganic me pada tha par yahan usse use karna hai kya pata nahi
11Arey, yeh complex terminology ko chodo.......back bonding and orbital resonance!! Speak in terms which everyone can understand!!
11backbonding in CCl2
I NEVER HEARD ABOUT IT[2]
DO TELL IF U KNOW[1]
1actually i wanted to ask fr backbonding then we ve opposite ans na crrct me if wrong
11cud we see d orbital resonance here just asking
@richa i coudnt get u could u explain clearly[1]
11aur Cl tho e- withdrawing bhi hai....us carbon ki positive charge aur bhi badegi.......isliye :CH2 hi better nucleophile hai
