Question

Which of the following is an interpseudohalogen (pseudohalogen analogues of interhalogen)?

• A. $HSCN$
• B. $ICN$
• C. $Br{F}_5$
• D. $C_2{N}_2$

Answer 1

Answer: (B)

• $F_2,C{l}_2,B{r}_2$ and $I_2=$ Halogen
• $ICl,IC{l}_3$, etc. = Interhalogen
• $\stackrel{-}{C}N,\stackrel{-}{S}CN,\stackrel{-}{O}CN=$ Pseudohalogen
• $ICN=$ inter pseudohalogen
