Q. What is the nature of the bond between B and O in $\left( C_{2}H_{5} \right)_{2}OBH_{3}$?
A) Covalent
B) Coordinate covalent
C) Ionic bond
D) Banana shaped bond
Explanation
(b)
Coordinate bond is formed.
$\left( C_{2}H_{5} \right)_{2}O \longrightarrow BH_{3}$
$\left( C_{2}H_{5} \right)_{2}O$ gives one lone pair of electron to $BH_{3}$. So, it is called electron pair donar and $BH_{3}$ is called electron pair acceptor.
