Q40. From the following, choose the one which are not secondary haloalkanes:
(A) 2-Bromopentane
(B)

Q: What is the correct answer for CUET UG Chemistry Q40?

The correct answer is a. A secondary haloalkane is one where the halogen atom is attached to a carbon atom that is bonded to two other carbon atoms.Let's determine the type of haloalkane for each option:(A) **2-Bromopentane:** CH₃-CH(Br)-CH₂-CH₂-CH₃. The carbon atom bonded to bromine is attached to two other carbon atoms (C1 and C3). So, this is a **secondary** haloalkane.(B) **1-Bromo-3-methylbutane:** CH₃-CH(CH₃)-CH₂-CH

A secondary haloalkane is one where the halogen atom is attached to a carbon atom that is bonded to two other carbon atoms.Let's determine the type of haloalkane for each option:(A) **2-Bromopentane:** CH₃-CH(Br)-CH₂-CH₂-CH₃. The carbon atom bonded to bromine is attached to two other carbon atoms (C1 and C3). So, this is a **secondary** haloalkane.(B) **1-Bromo-3-methylbutane:** CH₃-CH(CH₃)-CH₂-CH₂-Br. The carbon atom bonded to bromine (C1) is attached to only one other carbon atom (C2). So, this is a **primary** haloalkane.(C) **3-Bromopentane:** CH₃-CH₂-CH(Br)-CH₂-CH₃. The carbon atom bonded to bromine (C3) is attached to two other carbon atoms (C2 and C4). So, this is a **secondary** haloalkane.(D) **2-Bromo-2-methylbutane:** CH₃-C(Br)(CH₃)-CH₂-CH₃. The carbon atom bonded to bromine (C2) is attached to three other carbon atoms (C1, the methyl group, and C3). So, this is a **tertiary** haloalkane.(E) **2-Bromo-3-methylbutane:** CH₃-CH(Br)-CH(CH₃)-CH₃. The carbon atom bonded to bromine (C2) is attached to two other carbon atoms (C1 and C3). So, this is a **secondary** haloalkane.The haloalkanes that are *not* secondary are (B) 1-Bromo-3-methylbutane (primary) and (D) 2-Bromo-2-methylbutane (tertiary).Therefore, the correct choice is (B) and (D) only. This matches option (a).
