Question

Which is the correct IUPAC name for CC(C)CCBr (A) 1-Bromo-2-ethylpropane (B) 1-Bromo-2-ethyl-2-methylethane (C) 1-Bromo-2-methylbutane (D) 2-Methyl-1-bromobutane

Short answer

The correct IUPAC name for the compound is 1-Bromo-2-methylbutane.

Step-by-step solution

Identify the longest carbon chain

Identify the longest continuous carbon chain in the given compound. Here, the longest chain has 4 carbon atoms.

Number the carbon atoms in the chain

Assign a number (locant) to each carbon atom in the longest chain, starting from the end closest to the first substituent encountered. In our case, we'll start numbering from the end closer to Bromine.

Identify and number the substituents

Identify the substituents present in the compound and assign them locant numbers based on the carbon atom they are connected to. In our case, there is a Bromine atom attached to the 1st carbon and a methyl group attached to the 2nd carbon.

Assemble the IUPAC name

Arrange the substituents alphabetically in the name and use the numbering obtained in step 3. In our case, it would be "1-Bromo-2-methylbutane". Comparing to the given options: (A) 1-Bromo-2-ethylpropane (B) 1-Bromo-2-ethyl-2-methylethane (C) 1-Bromo-2-methylbutane (D) 2-Methyl-1-bromobutane Our correct name matches with option (C), so the correct IUPAC name for the given compound is: 1-Bromo-2-methylbutane.
