Knowledge Check

  • The IUPAC name of any organic compound consists of four parts, i.e., word root, primary and secondary suffixes and prefixes. The word root denotes the total number of carbon atoms in the longest continuous chain of carbon atoms present in the molecule. The primary suffix denotes whether the compound is saturated (i.e., ane) or unsaturated (i.e., ene or yne) while the secondary suffix denotes the functional group present in the molecule. The primary prefix cyclo is used only when the compound is cyclic in nature while the secondary prefixes denote the substituents and secondary functional groups, if any. The IUPAC name of the compound CH_(3)-CH_(2)-CH_(2)-CH_(2)-OH is

    A
    butanol
    B
    butanal
    C
    butene
    D
    propanol
