MCQ Questions for Class 12 Chemistry with Answers were prepared based on the latest exam pattern. R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.Sometimes used more loosely, to include other elements such as halogens, oxygen, or nitrogen. There are methyl and ethyl groups (rule 2), both attached to the fourth carbon atom (counting from the right gives this carbon atom a lower number; rule 3). Therefore it is to be written first in the name and to be given the lowest number. Hence 'methyl' group is given the lower number according to the rule of first point of difference.
