The name of the substance, the formula of which is CH2 (H3C) – CH (OH) – CH – CH3 (CH3)

To form the name of a substance, it is necessary to choose the longest possible carbon chain and number the atoms in it. The numbering starts from the end to which the senior functional group is closer. In our case, the hydroxyl group is located in the center of the carbon chain, so we will number from the end, which is closer to the -CH3 substituent (from the right). The only functional group in the proposed compound is hydroxyl, its presence is indicated by the suffix “-ol” at the end of the name. The positions of substituents and functional groups are indicated by numbers in the name.

H3C – CH2 – CH (OH) – CH – CH3 (CH3);

IUPAC systematic name of the substance:

2-methylpentanol-3.
