    option D

    eduncle-logo-app

    it show back bonding so it is plannar shape molecule

    eduncle-logo-app

    got it?

    eduncle-logo-app

    due to bulky groups option the given molecules in option A and B are non planar

    eduncle-logo-app

    while NF3 is sp3 hybridised having one lone pair so it has pyramidal shape

    eduncle-logo-app

    so only one option D is absolutely correct

    Option D

    eduncle-logo-app

    empty d orbital on Si and lone pair on nitrogen go in empty d orbital...so planar

    eduncle-logo-app

    d pi- p pi backbonding occurs here

    eduncle-logo-app

    sir what about NPh3 ??

    eduncle-logo-app

    see

    eduncle-logo-app

    you must have empty d orbital na...

    eduncle-logo-app

    Here in trisilyl amine...empty d orbital on silicon

    eduncle-logo-app

    NPh3 me b toh lone pair delocalisation me jayenge

    eduncle-logo-app

    so NPh3 b planar hona chahiye ?

    eduncle-logo-app

    shristy...d pi -p pi backbonding case

    eduncle-logo-app

    yha pe empty d orbital nhi na hai

    eduncle-logo-app

    ok sir agr dpi- ppi case ni hota toh NPh3 will b planar ?

    eduncle-logo-app

    or agar ye ques msq me aata tb ??

    eduncle-logo-app

    shristy triphenyl amine is typically non planar

    eduncle-logo-app

    It is propeller molecule...it propells or rotate due to its special shape.. https://youtu.be/pRTTRbORIcg see this video

    eduncle-logo-app

    got this shristy?
