In this problem, how do you know which atoms or groups are
going away, towards you, or in plane from the chiral center? for
example, why do they assume that hydrogen is going away (dotted
line) and Ch3 is coming towards you (bold colored line)? And how do
you know which direction Ch2Ch2Br and Br is going in? its just a
single line (Not dotted or bold). I know directions are important
in determining R/S.
