    See cip rule has no reason, it just a matter of convenience we have framed such rule to differentiate two compound on paper. R configuration may rotate the light clockwise or anticlockwise. R or S is just a name by rule & you have to memorize the rule and practice the question. please rate my answer as feedback are most important to improve the quality of answer

    In assigning R/S in such problem always apply numbering according to cip to planar side and then to non planar side. If 4th is dash then clockwise R . If 4th is on wedge then clockwise S
