Write the IUPAC name of the compound `CH_3 CH_2 - undersetoverset(|)(OH)(C)H - CH_3`

Explanation

(a) There are 4 atoms in the longest continuous chain involving-OH group, therefore, the root word is .but..
(b) Only C-C bonds appear in the carbon chain, therefore, primary suffix is .ane..
(c) There is -OH group at carbon 2 of the chain, therefore, secondary suffix is .2-ol..
Base name = root word + primary suffix = but + ane - butane
Thus, the IUPAC name of the given compound is derived as:
Butane named - e + Secondary suffix
Butane - e + 2-ol = Butan-2-ol
