  • BCl_3 does not exist as a dimer but BH_3 exists as B_2H_6 because:

    A
    Chlorine is more electronegative than hydrogen
    B
    Large size of chlorine atom does not fit between small, sized boron atoms, while small-sized hydrogen atoms occupy the space between boron atoms.
    C
    There is `p pi-p pi` back bonding in `BCl_3`.
    D
    Both (B) and (c)
  • BCl_3 does not exist as a dimer but BH_4 exists as B_2H_6 because:

  • A compound exists in the gaseous state both as monomer ( A_(1) ) and dimer ( A_(2) ). The molecular weight of the monomer is 48. In an experiment, 96 g of the compound was confined in vessel of volume 33.6 L and heated to 273^(@) C. Calculate the pressure developed, if the compound exists as a dimer to the extent of 50% by weight under these conditions.
