Two students were given the task to prepare an adduct $NH_3 \to BH_3$ at low temperature :-
Student $I$ :- She mixed $B_2H_6$ and $NH_3$
Student $II$ :- He mixed $B_2H_6$ with $THF$ followed by addition of $NH_3$
Which student is expected to get the $CORRECT$ final product ?
$I$ only
$II$ only
Both $I$ and $II$
Neither $I$ nor $II$
Which of the following have $3C-2e^-$ bond
$I.$ $Al_2Cl_6$ $II.$ $B_2H_6$
$III.$ $Fe_2Cl_6$ $IV.$ $Si_2H_6$
When orthoboric acid $({H_3}B{O_3})$ is heated, the residue left is
Aluminium chloride exists as a dimer, $Al_2Cl_6,$ in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives:
Explain what happens when boric acid is heated.
Explain ionization enthalpy and electro-negativity for elements of Boron family.
