Example neopentane is CH3C(CH3)2 - CH3 Prefix sec- is used for those carbon atoms which are joined to two other carbon atoms. Example             I CH3 -CH-CH3 Prefix tert- is used for those carbon atoms which are joined to three other carbon atoms. Example             I CH3 -C-CH3            I          CH3 iso and neo are basically used for alkyl groups and sec and tert are used for carbon atoms which have functional groups, charge or are radicals.
