How are the two BRs related and how are the OH figures related

Solve correctly please. Should 100% sure of final answer with some explanation of them.

Please show work on paper and circle final answer

Need help with number 4. Theses are pre lab questions and not homework. Was rejected once and unsure why. Pre lab means before the actually lab we do (which that part is graded) Thanks
