WebNH 3 is a lewis base. Because one lone pair is present in ammonia. So, it can donate its lone pair. (B) NH 4 + is not a lewis acid, all atoms are in the stable configuration in this species. So, it can not accept an electron pair. (D) H 2 O is also a lewis base. Because two lone pair is present in the water. So, it can donate its lone pair.
