Which one of the following is the correct statement?
Options
- ABoric acid is a protonic acid
- BBoth T l 3 + and A l 3 + ions act as oxidizing agent in aqueous solution.
- CHydrogen bonding in H 3 B O 3 gives it a layered structure.
- DB ( O E t ) 3 imparts blue colour to the burner flame.
Correct answer
C. Hydrogen bonding in H 3 B O 3 gives it a layered structure.
Step-by-step solution
It acts as a lewis acid by accepting eletrons from a hydrogen ion and it turn releases H + ions T l + 3 acts as on oxidizing agent A l + 3 acts as reducing agent because the stability of lower oxidation state on moving down the group in increases due to pair effect stability T l + 3 pair effect stability T l + 1 > T l + 3 Hydrogen bonding in H 3 B O 3 gives it a layered structure. B ( O E t ) 3 imparts green colour to the burner flame.
