Question

Q. No. 23 CH3 - CH2 - CH2 - Br has sets of the equivalent protons. Select the correct answer A) 1 B) 2 C) 3 D) 4​

Answer 1

Answer:

1 ) bromine has only one proton

Answer 2

Sets of equivalent protons CH₃-CH₂-CH₂-Br

Explanation:

• Equivalent protons are those protons which are present in same environment. Non equivalent protons are those which are present in different environment.
• In the given organic compound i.e. 1-Bromopropane contains total 7 protons. Molecular formula of 1-Bromopropane is -

                C₍₃₎H₃-C₍₂₎H₂-C₍₁₎H₂-Br

• C₍₁₎ in above compound contains 2 protons and both protons present in same environment.
• C₍₂₎ contains 2 protons and these protons also present in same environment.
• C₍₃₎ contains 3 protons which are present in same environment.
• But C₍₁₎, C₍₂₎ and C₍₃₎ protons present in different environment from each other other.
• So, given organic compound has 3 sets of equivalent protons.

Therefore, CH₃-CH₂-CH₂-Br contains 3 sets of equivalent protons.
