Which group has greater steric hindrance?

AI Thread Summary
The discussion centers on the comparison of steric hindrance between an amino group (NH2) and an ethyl group (CH2CH3). The primary point of analysis is based on molecular size, with the ethyl group having a molecular weight of 29 g/mol compared to the amino group's 16 g/mol. This size difference indicates that the ethyl group exhibits greater steric hindrance than the amino group. The conclusion drawn is that when assessing steric hindrance, size is a key factor, and in this case, the ethyl group is larger and thus more hindering.

Does an amino group or ethyl group have greater steric hindrance?
Is there a "rule" that I can follow to determine this?

Rule 1: "Size." So, you tell me which is larger?

Well the molecular weight of CH2CH3 is 29g/mol, and NH2 is 16g/mol. Ethyl is larger, so I guess I have my answer then!
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
