Question

Consider borazine halides $B_3{N}_3{H}_{(6-n)}C{l}_n$ where n ranges from 1 to 6. Correct option(s) is/are ______.

• A. On increasing n number of position isomers increases monotonically
• B. Number of position isomers is 4 only if n=2
• C. Number of position isomers is 6 only if n=3
• D. Number of position isomers is 2 only if n=1

Answer 1

The correct option is C Number of position isomers is 6 only if n=3

n=1 or 5 PI=2, n=2 or 4 PI=4, n=3 PI=6

n = 5 two P.I




n = 4
Just replace Cl with H and H with Cl for n=2 and we get for n=4.
we will get 4 positional isomers.
