A mixture of Boron trichloride and hydrogen is subjected to silent electric discharge to form x and HCl . x is mixed with NH 3 and heated to 200 0 C to form y . The formula of y is
Options
- AB 2 O 3
- BB 3 N 3 H 6
- CH 3 BO 3
- DB 2 H 6
Correct answer
B. B 3 N 3 H 6
Step-by-step solution
When a mixture of BCl 3 and H 2 is subjected to silent electric discharge, diborane and HCl are formed. Diborane reacts with NH 3 at 200 ° C to give Borazine (inorganic benzene). 2 BCl 3 + 6 H 2 → discharge Electric B 2 H 6 x + 6 HCl 3 B 2 H 6 1 + 6 NH 3 2 ⟶ 200 ° C 2 B 3 N 3 H 6 Borazine ( y ) + 12 H 2
