IUPAC name of neopentyl chloride is

The correct answer is Option (1) → 1-Chloro-2,2-dimethylpropane

Neopentyl chloride is \( \ce{(CH3)3C-CH2Cl} \). The longest chain containing the carbon bearing Cl has three carbon atoms (propane). Numbering from the end nearer to Cl puts Cl on C-1 and the two methyl groups on C-2:

    ¹CH₂Cl–²C(CH₃)₂–³CH₃

IUPAC name: 1-Chloro-2,2-dimethylpropane.
