Borazine, also known as inorganic benzene, can be prepared by the reaction of \( 3 \)-equivalents of “X” with \( 6 \)-equivalents of “Y”. “X” and “Y”, respectively are:
\( \mathrm{B(OH)_3} \) and \( \mathrm{NH_3} \)
\( \mathrm{B_2H_6} \) and \( \mathrm{NH_3} \)
\( \mathrm{B_2H_6} \) and \( \mathrm{HN_3} \)
\( \mathrm{NH_3} \) and \( \mathrm{B_2O_3} \)
