Question

In complex hydrides, hydride ions act as ligand and are coordinated to metal ions. These hydrides are good reducing agents. Which of the following hydrides is not a complex hydride?
  1. NaBH4
  2. LiAIH4
  3. (AlH3)n
  4. LiBH4

A
LiAIH4
B
LiBH4
C
NaBH4
D
(AlH3)n
Solution
Verified by Toppr

(AlH3)n is a polymeric hydride like (BeH2)n,(MgH2)n etc.
Whereas, LiAlH4, NaBH4 and LiBH4 are complex co-ordinate hydrides.
Hence option C is correct.
