Question

Structure of boric acid is

• A. tetrahedral
• B. trigonal
• C. layer structure in which $\ce{BO_3}$ units are linked through oxygens
• D. layer structure in which planar $\ce{BO_3}$ units are linked by H-bonding

Answer 1

Answer: (D)

layer structure in which planar $\ce{BO_3}$ units are linked by H-bonding

Answer 2

Boric acid ${(H_3BO_3)}$ contains ${BO_3}$ units which are planar and linked together by H-bonding to give layer structure
