Question

Boric acid $\left(H_{3}B{O}_3\right)$ has:

• A. trigonal structure
• B. tetrhedral structure
• C. layer structure, in which $B{O}_3$ units are linked by oxygen
• D. layer structure, in which planar $B{O}_3$ units are linked by hydrogen bondining

Answer 1

Answer: (D)

layer structure, in which planar $B{O}_3$ units are linked by hydrogen bondining

.The central boron atom is connected to three hydroxyl (-OH) groups, which are capable of strong hydrogen bonding. Its solid crystalline structure consists of parallel layers of boric acid held together in place by hydrogen bonds.
