Q6.2(i):
Give the IUPAC names of the following compounds: (i) ( CH_{3}CH(Cl)CH(Br)CH_{3} )

Solution :

Step 1: Identifying the Longest Carbon Chain

The structural formula given is $CH_3-CH(Cl)-CH(Br)-CH_3$. We observe a continuous chain of four carbon atoms. Therefore, the parent alkane is butane. [Per IUPAC nomenclature rules for selecting the principal carbon chain].

Step 2: Numbering the Carbon Chain

To assign locants to the substituents (Chloro and Bromo groups), we must number the chain from the end that yields the lowest possible set of locants. [Per the Lowest Locant Rule]:

  • Numbering from left to right: Substituents are at positions 2 and 3.
  • Numbering from right to left: Substituents are at positions 2 and 3.

Since the locant set is identical $(2, 3)$ from both directions, we apply the Alphabetical Priority Rule. We choose the numbering direction that assigns the lower number to the substituent that comes first alphabetically. [Per IUPAC Rule P-14.4].

  • Bromo ($B$) precedes Chloro ($C$).
  • Assigning 2 to Bromo forces numbering from the right: $CH_3(4)-CH(Br)(3)-CH(Cl)(2)-CH_3(1)$.
  • Assigning 2 to Chloro forces numbering from the left: $CH_3(1)-CH(Cl)(2)-CH(Br)(3)-CH_3(4)$.

Since 'B' in Bromo comes before 'C' in Chloro, we assign the position 2 to the Bromo group. Therefore, the chain is numbered from right to left.

Step 3: Constructing the IUPAC Name

The substituents are identified as 2-bromo and 3-chloro. Combining these with the parent chain "butane" in alphabetical order:

Component Value
Substituent 1 2-Bromo
Substituent 2 3-Chloro
Parent Chain Butane

Hello, my name is Atulya Kumar. I have completed my engineering from IIT (ISM), Dhanbad and am currently pursuing a PhD in Civil Engineering at IIT (ISM), Dhanbad. Teaching physics has been both a passion and a purpose since 2019, and over the years, I have mentored Class XI and XII students, particularly those preparing for JEE Main, JEE Advanced, NEET, and board examinations. I specialize in teaching Class 12 Physics in a result-oriented and concept-focused manner. My classes are tailored to bridge the gap between theory and application, ensuring students not only understand the fundamentals but can also apply them effectively in competitive exams. In recent years, my students have consistently performed exceptionally well. For example, in NEET 2025, two of my students scored 653 and 639, while many achieved more than 99 percentile in JEE Main 2025. In earlier years, students under my guidance secured AIR 2513 in NEET 2022 and AIR 1702 in NEET 2023, with many crossing the 98th percentile in JEE Main 2023. I adopt a structured approach, focusing on topic-wise concept clarity, MCQ drills, PYQ (previous year questions) practice, and mock test simulations. My JEE sessions emphasize critical topics such as modern physics, electromagnetism, kinematics, and thermodynamics, while NEET classes are tailored toward speed, accuracy, and NCERT alignment. I also give equal importance to board exam preparation, guiding students to score above 90% in Physics through clear explanations, derivation practice, answer writing techniques, and mock board tests. Teaching physics is a personal challenge and joy for me. I strive to build a learning environment where students feel confident, curious, and capable. It’s deeply fulfilling to watch them grow from conceptual struggles to academic excellence, and I remain committed to their success—both in exams and in life.
