Give reasons for the following:
`CH_2=CH^(Θ)` is more basic than `HC-=C^(Θ)`

Give reason for the following : CH_2=CH^- is more basic than HC≡C^- .

Explain: CH_(2) = CH^(-) is more basic than HC -= C^(-)

Account for the following (CH_(3))_(2)NH is more basic than (CH_(3))_(3)N in an aqueous solution.

CH_(3)- NH_(2) is more basic than ammonia . Why ?

Give the number of strong field ligand(s) from the following NH_(3),en, CI^(Θ),CH_(3)COO^(Θ),overset(Θ)(CN),CO,NO_(2)^(Θ) .
