Multiple choice question:

Why is LiAlH4 more reactive than NaBH4?

a. Al is less electronegative than B, meaning there is a greater concentration of negative charge on H when bonded to Al

b.H is bonded to both Li and Al in LiAlH4, making it more unstable and therefore more reactive

c.The Li+counterion is smaller than Na+, so there is reduced steric bulk in LiAlH4

d.The Al-H bond is longer, and so it is easier to break for a reaction to occur
