What should be the correct IUPAC name for diethylbromomethane?

(i) 1 -Bromo- 1,1 -diethylmethane

(ii) 3-Bromopentane

(iii) 1-Bromo-1-ethylpropane

(iv) 1-Bromopentane

<p><span data-teams="true">This is a multiple choice answer as classified in NCERT Exemplar</span></p><p>The Correct Answer is Option (ii).</p><p>We may conclude from the given compound's common name that there are two <strong>-C₂H₅</strong> groups and one <strong>-Br</strong> group linked to a <strong>CH₄</strong> molecule. Bromomethane would be represented by the symbol <strong>CH₃-Br</strong>. Two ethyl groups can be replaced for the hydrogens in the methyl molecule to make diethylbromomethane <strong> (C₂H₅)CH (C₂H₅)Br</strong>. The longest parent chain must be identified in order to offer an IUPAC name. The parent chain is <strong>CH₃-CH₂-CH (Br)-CH₂-CH₃</strong>, with the <strong>-Br</strong> group from either side connected to the third carbon atom. Because the parent chain has five carbons, the molecule is termed 3-bromopentane.</p>
