Lyman series (n? = 1)

Balmer series (n? = 2)

Paschen series (n? = 3)

Brackett series (n? = 4 )

Pfund series (n? = 5)

Humphreys series (n? = 6)

Further series are unnamed, but follow exactly the same pattern as dictated by the Rydberg equation. Series are increasingly spread out and occur in increasing wavelengths. The lines are also increasingly faint, corresponding to increasingly rare atomic events.

when an electronegative element is added to the carbon chain .the carbon chain gets more electronegativity as a result there is a shift of charge from one carbon and the effect lessens upto the second carbon and then to the third ,,after third  the effect is negligible...we call it inductive effect..there are to effects + I and -I effect or electron withdrawing and electron donating effect....

inductive effect is the polarity produced between two atoms or groups wen carbon atom is attached to electron-withdrawing or electron-releasing groups
