Which group has greater steric hindrance?

    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!
