विकल्प

• 1-bromobutane

• 2-bromobutane

• 1-bromo-2-methylpropane

• 2-bromo-2-methylpropane

Answer 1

The IUPAC name of sec-butyl bromide is 2-bromobutane.

Explanation:

sec‑butyl bromide has the skeleton CH₃ − CH(Br) − CH₂ − CH3. The longest chain is butane (4 C), and the bromo substituent is on C‑2, so the IUPAC name is 2-bromobutane.
