You needed to make sure your glassware was dry before proceeding with the hydroboration reaction and an excess of hydroborane was used to counter the small amounts of water present in the reaction. Why is the borane-THF reagent so reactive with water? Hint: What is the electronegativity of B compared to H?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
