R-6.1 6-(4-Hydroxyhex-1-en-1-yl)undeca-2,4-diene-7,9-diyne-1,11-diol

(a) The term 'undeca' in this name indicates the presence of the 11-carbon saturated parent hydride undecane.

The suffix '-ol' with its multiplicative prefix 'di-' and locants '1' and '11' indicates the presence of two hydroxy () groups at positions 1 and 11 of undecane. The infixes '-ene' and '-yne', with their multiplicative prefix 'di-' and locants '2' and '4', and '7' and '9', describe double bonds at positions 2 and 4 and triple bonds at positions 7 and 9, respectively.

The resulting parent structure with its numbering is:

(b) The complex prefix '(4-hydroxyhex-1-en-1-yl-)' with its locant '6' describes a substituent at position 6 of the parent structure. The parent substituent is a six-carbon chain corresponding to the parent hydride name 'hexane'. The prefix 'hydroxy-' with its locant '4' denotes a hydroxy group at position 4; and the infix '-en-' with its locant '1' and the suffix '-yl-' with its locant '1' describe, respectively, a double bond at position 1 and a free valence at position 1. Hence, the structure and numbering of the complex substituent is:

(c) The structure of the complete compound is therefore:
