C2h5nh2 C6h5nhch3 C2h5 2nh And C6h5nh2 2024. (i) in decreasing order of pkb values : \[\ce{c6h5nh2, c6h5nhch3, c6h5ch2nh2, ch3nh2, nh3}\] state one reason for the following:
Among c 2 h 5 nh 2 and (c 2 h 5)nh, (c 2 h 5) 2 nh is more basic than c 2 h 5 nh 2 due to the greater +i effect of the two c 2 h 5 groups and stabilization of its conjugate acid by h. (iii) increasing order of basic strength.
