Pz solve question 2 and explain

sir can u pz explain non classical and classical bonding

shib have you read about classical and non classical carbocation

sir i just read that only sigma donors r classical and sigma donor & π acceptor is non classical

see

vacant d orbitals are also present in phosphine to accept LP...

So all the three sigma,pi and d orbitals are used

When acting as a ligand to a metal centre, carbon monoxide is capable of forming a metal-carbon σ bond via donation of a lone pair from carbon. It can also accept π-electron density from filled d-metal orbitals into the CO π antibonding orbital.

got shib??

please accept the answer shib if you got it😊🙏

dear shib??

sir can u please explain

See this

Is MSQ question Shib

no sir but answer is option d

See this example

Let me check if sigma is also involved

https://youtu.be/alk8BrhdmOU . little longer but complete details

See this

option D is correct. Actually these questions you can easily answer by knowing of definition only of non classical ligand

Carbonyls bound to very poor π-donor metals have very high frequency ν(CO) bands as a result of weak back donation. When these appear to high energy of the 2143 cm−1 band of free CO, the complexes are sometimes called non-classical carbonyls. )(CO)] has a ν(CO) stretching frequency of 2057 cm−1.

so here only sigma bonding present in case of non classical compounds

sir this question is from coordination

metal carbonyl also the part of coordination compunds

sir question 2

please wait
