$a, b$

Vedclass · Answer

(A) $1.$ In orthoboric acid $H_3BO_3$, boron is $sp^2$ hybridized and thus has a planar geometry.$2.$ In $BCl_3 \cdot NH_3$, boron is $sp^3$ hybridized due to the formation of a coordinate bond with $NH_3$, resulting in a tetrahedral geometry.$3.$ Borax is a salt of a strong base $(NaOH)$ and a weak acid $(H_3BO_3)$. Therefore, its aqueous solution is basic in nature, not acidic.Thus, statements $(a)$ and $(b)$ are correct.

Identify the correct statements from the following:
$(a)$ In orthoboric acid, boron is in planar geometry.
$(b)$ In $BCl_3 \cdot NH_3$, boron has tetrahedral geometry.
$(c)$ Aqueous solution of borax is acidic.
