MCQ
What is the nature of the bond between $B$ and $O$ in ${({C_2}{H_5})_2}OB{H_3}$
- ACovalent
- ✓Co-ordinate covalent
- CIonic bond
- DBanana shaped bond
✓
Answer
Correct option: B.
Co-ordinate covalent
b
$As BH _3$ is a lewis acid, it can accept a lone pair of electron donated by alkoxy group hence the bond formed is co-ordinate covalent bond. $\left( C _2 H _5\right)_2 O$ gives one lone pair of an electron to $BH _3$. So, it is called the electron-pair donor.
