btw platinum is more reactive than gold right?
not sure, some websites give platinum as more reactive while others give gold.(my teacher said it is gold which is more reactive)
anyway i dont think u will need this comparission because both of them are almost non reactive with other metals and are found free in nature.

I am Having trouble with the alpha and beta :/ i just cant state the difference?!
alpha is havier and slower than beta and has stronger ionising effect. it is +vely charged while beta is -vely charged. alpha is stopped by a thin sheet of paper it travels to shorter distances compared to beta and is less penetrating.

i asked because both aldehyde and ketone undergoes nuclophilic addition
carboxylic acid also have cabonyl group why it does not undergoes nuclophilic addition by HCN
