banana bonding

When as inorganic compound X having electron dificient bounding (banana bonding ) react with ammonia gas at certain temperature gives a compound (Y) , isostructural with benzene. Compound (X) with ammonia at a high temperature produces a substance (Z) .

In diborane, the banana bond is formed between

In which of the following compounds banana bond is present ?

Which of the following statement is is/are true - (I) Borazine is aromatic (II) There are four isotopic disubstitued borazine molecules B_(3)N_(3)H_(4)X_(2) (III) Borazine is more reactive towards additon reaction then benzene (IV) Banana bonds in B_(2)H_(6) are longer but stronger than normal B-H bonds
