The incorrect statement from the following for borazine is:

(A)It has electronic delocalization
(B)It contains banana bonds.✓ Correct
(C)It can react with water.
(D)It is a cyclic compound.

Answer: (B)

Solution

Borazine,

B_{3} N_{3} H_{6}

, is a six-membered cyclic compound that is isoelectronic with benzene and shows

π

-electron delocalisation over the ring. It is hydrolysed by water to give ammonia, boric acid and hydrogen. Its B–N and N–H linkages are ordinary two-centre two-electron bonds; bent or banana bonds belong to electron-deficient bridged systems such as diborane, not to borazine. The statement that borazine contains banana bonds is therefore incorrect.
