In this paper, we discussed all extremal connected graphs among the class of bicyclic and tricyclic graph by using the first general Zagreb index for minimum and maximum for , also for first multiplicative Zagreb index for minimum and maximum for , maximum second Zagreb multiplicative index ) and minimum first coindex among above mentioned graphs with the given diameter respectively
