first substituent at C3 first substituent at C2 Page 142 If the first substituent is the same distance from both ends, number the chain to give the second substituent the lower number. Always look for the first point of difference in numbering from each end of the longest chain. Incorrect Correct 5 CH3 groups at C2, C4, and C5 The second CH3 group has the higher number (C4). CH3 groups at C2, C3, and C5 The second CH3 group has the lower number (C3) When numbering a carbon chain results in the same numbers from either end of the chain, assign the lower number alphabetically to the first substituent. Incorrect Correct 3 4 methyl ethyl up
