    For ques 2 option D is correct...All orbital of ligand participate in bonding in non classical compound

    eduncle-logo-app

    sir can u pz explain non classical and classical bonding

    eduncle-logo-app

    shib have you read about classical and non classical carbocation

    eduncle-logo-app

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

    eduncle-logo-app

    see

    eduncle-logo-app

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

    eduncle-logo-app

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

    eduncle-logo-app

    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??

    eduncle-logo-app

    please accept the answer shib if you got it😊🙏

    Q 2 pi option A is correct

    eduncle-logo-app

    sir can u please explain

    Is MSQ question Shib

    eduncle-logo-app

    no sir but answer is option d

    eduncle-logo-app

    See this example

    eduncle-logo-app

    Let me check if sigma is also involved

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

    check the concept of classical and non classical compounds

    eduncle-logo-app

    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.

    eduncle-logo-app

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

    eduncle-logo-app

    sir this question is from coordination

    eduncle-logo-app

    metal carbonyl also the part of coordination compunds
