However, in CH3CHCI2, the chlorine atom is attached to the second carbon atom in the chain, while in CH2CI, the chlorine atom is attached to the first carbon atom in the chain.<\/p>\n<p>Therefore, CH3CHCI2 and CH2CI are positional isomers.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>Chain isomerism<\/strong> is a type of structural isomerism in which two or more compounds have the same molecular formula but different carbon skeletons. For example, butane (C4H10) and 2-methylpropane (C4H10) are chain isomers.<\/li>\n<li><strong>Functional group isomerism<\/strong> is a type of structural isomerism in which two or more compounds have the same molecular formula but different functional groups. For example, ethanol (C2H6O) and dimethyl ether (C2H6O) are functional group isomers.<\/li>\n<li><strong>Metamerism<\/strong> is a type of structural isomerism in which two or more compounds have the same molecular formula and the same functional group but different alkyl groups attached to the functional group.
