The base with lowest $pK_{a}$ value is

Options:

Answer:

Solution:

Low value of pKa means stronger acid or weaker base. Thus as basicity decreases pKa value decreases. Due to presence of strong electron withdrawing (−I effect), NCCH₂NH₂is the weakest base as it has the lowest electron density on N−atom. Hence, NCCH₂CH₂ has the lowest pKa value.
