Which statement below is false concerning nomenclature rules for alkanes?
1) The name of the alkane is written as a single word.
2) Carbon atoms are numbered starting with the atom farthest from the branching point.
3) The parent name is taken from the longest continuous chain of carbon atoms.
4) Each branching group is assigned a number referring to its point of attachment in the parent chain.
I think it is 2) because I know 1) and 3) are correct
To determine which statement below is false concerning nomenclature rules for alkanes, we will analyze each statement:
1) The statement "The name of the alkane is written as a single word" is true. In alkane nomenclature, the name of the compound is written as a single word, with no spaces or punctuation marks.
2) The statement "Carbon atoms are numbered starting with the atom farthest from the branching point" is true. In alkane nomenclature, carbon atoms in the main chain are numbered in such a way that the numbering starts from the end that is farthest from any branching or substituent groups.
3) The statement "The parent name is taken from the longest continuous chain of carbon atoms" is true. The parent chain in alkane nomenclature is determined by selecting the longest continuous chain of carbon atoms in the molecule.
4) The statement "Each branching group is assigned a number referring to its point of attachment in the parent chain" is false. In alkane nomenclature, each branching group is assigned a locant or a number that corresponds to its point of attachment in the parent chain. However, the locant is not necessarily the actual number of the carbon atom to which the branching group is attached.
Based on the analysis above, statement number 4 is the false statement concerning nomenclature rules for alkanes.
