Q. The strongest base is
A) [image:7_image1.emf]
B) [image:7_image2.emf]
C) [image:7_image3.emf]
D) [image:7_image4.emf]
Explanation
(a)
According to lewis, a base is a species that can donate a pair of electrons to an acid to form a coordinate bond,
[image:7_image13.emf]
is a secondary amine. It also has a lone pair of electrons in $sp^{3}$ hybridised orbital which can easily be donated. Therefore, it is the strongest base.
