Understanding Borax Structure
Borax, or sodium tetraborate, is a naturally occurring mineral with a complex crystalline structure. The correct answers regarding its crystalline form are options A, C, and D.
Tetranuclear Unit
- The crystalline structure of borax features a tetranuclear [B4O5(OH)4]2– unit.
- This unit consists of four boron atoms interconnected through oxygen atoms and hydroxyl groups, showcasing the interconnected nature of boron in borax.
Boron Hybridization
- In borax, there is an equal number of sp2 and sp3 hybridized boron atoms.
- The sp2 hybridization occurs in the planar arrangement of the boron atoms within the borate groups, while sp3 hybridization occurs in the tetrahedral coordination of some boron atoms with hydroxyl groups.
Terminal Hydroxide Groups
- Each boron atom in borax indeed has one terminal hydroxide (–OH) group.
- This structural feature contributes to the compound's overall stability and reactivity, making it useful in various applications.
Summary
In summary, the crystalline structure of borax is characterized by:
- Tetranuclear [B4O5(OH)4]2– unit: Central to its structure.
- Equal boron hybridization: Both sp2 and sp3 present.
- Terminal hydroxide per boron atom: Enhances stability and reactivity.
These features collectively explain why options A, C, and D are correct regarding the crystalline form of borax.
