Rutherfords experiment showed that most of the alpha particles passed through a thin gold foil undeflected. So why can't light pass through the foil, which is supposedly thinner than the heavy alpha particles?
I have a linear butane whose second carbon from the left is bonded to a chlorine and then the third carbon is bonded to two methyls. Am I correct in naming this 2-chloro - 3,3-dimethyl - butane ?
My doubt comes from the fact that both ends of the chain are next to a carbon which ramifies. I know the simpler ramification is the one that "prevails". So I would think the question can be reformulated: is chlorine simpler than two methyls?
