The arrangement of $CH_3-CH_2-CH_2-$,$(CH_3)_2CH-$,and $(CH_3)_3C-$ groups in increasing order of their inductive effect ($+I$ effect) is:
- A$(CH_3)_3C- < (CH_3)_2CH- < CH_3-CH_2-CH_2-$
- B$CH_3-CH_2-CH_2- < (CH_3)_2CH- < (CH_3)_3C-$
- C$(CH_3)_2CH- < (CH_3)_3C- < CH_3-CH_2-CH_2-$
- D$(CH_3)_3C- < CH_3-CH_2-CH_2- < (CH_3)_2CH-$
