what is the conflicts and how do they differ from the chapters 5 and 6

Chapter five continues with Ralph's conflicts as leader. The weight of leadership becomes oppressive for Ralph as the story continues; he is dutiful and dedicated, but his attempts to instill order and calm among the boys are decreasingly successful. Golding develops Ralph's particular concerns and insecurities in this chapter. By showing him brooding over his perceived failures, Golding highlights Ralph's essentially responsible, adult nature. Jack's aggressive and dominating nature is too much for the reflective and practical Ralph to counter.   

Chapter six differs from chapter 5 in that the concept of fear and the beast is tested. Jack is eager to portray Ralph as weak and ineffective when it comes to fear and the beast.
