    An example for a saturated fatty acid, present in nature is [KCET 2005]

    A)                 Oleic acid            

    B)                 linoleic acid

    C)                 Linolenic acid    

    D)                 Palmitic acid

    Correct Answer: D

    Solution :

    Oleic acid - \[{{C}_{17}}{{H}_{33}}COOH\], linoleic acid- \[{{C}_{17}}{{H}_{31}}COOH\], linolenic acid - \[{{C}_{17}}{{H}_{29}}COOH\], palmitic acid - \[{{C}_{15}}{{H}_{31}}COOH\]. Saturated monocarboxylic acids form a homologous series which has a general formula \[{{C}_{n}}{{H}_{2n+1}}COOH\] or \[{{C}_{n}}{{H}_{2n}}{{O}_{2}}\]. Only palmitic acid follows this.
