According to Lewis, "A base is a species which can donate an electron pair." In NH3, overset⋅ ⋅ N has one lone pair. Thus, overset⋅ ⋅ NH3 is a Lewis base.

Q. Which is a Lewis base?

$B_{2} H_{6}$

$L i A l H_{4}$

$A l H_{3}$

$N H_{3}$

According to Lewis, "A base is a species which can donate an electron pair." In $N H_{3}, N \cdot\cdot$ has one lone pair. Thus, $N \cdot\cdot H_{3}$ is a Lewis base.
