Find total number of species which are non planar out of following
B₂H₆, C₂F₆, Be₂H₄, CH₃, SF₆, N(SiH₃)₃
Options:
Answer:
B
Solution:
B₂H₆, C₂F₆, CH₃⁻, and SF₆ are non-planar because they have three-dimensional geometries (bridged-perpendicular, tetrahedral, trigonal pyramidal, and octahedral, respectively).
Be₂H₄ is planar as all of its constituent atoms lie within the same single plane.
N(SiH₃)₃ is planar due to pπ-dπ back-bonding from nitrogen's lone pair into silicon's empty d-orbitals, forcing a trigonal planar structure.
