Question

I don't understand what monohalogenation is and what the question is asking exactly. can somone please help with explaining and not just answering the question? thank you very much im advance.

20. For each compound in Problem 15, determine how many constitutional isomers can form upon monohalogenation. (Hint: Identify all groups of hydrogens that reside in distinct structural environments in each molecule.)

Answer 1

from → Monohalogenation means replacement of one H-atom the substrate by a halo (X=Cl, Br,I) atom. Constitutional isomes means the compounds with similar molecular formula but molecular structures, CH₃ - CH₂ - CH₂ - CH3 by can form two different monohalogenated products, 1- CH₃-CH-CH₂-CH3 2- CH₂ - CH₂-CH₂-CH3 Br (2- bromobutane) B1 (1-botamobutane) CH₃ - CH₂ - CH₂ - CH₂-CH3 Can form three different monohalogenated products. D) CH2-CH2-CH2-CH2-CH3 2) CH3-CH-CH2-CH2-CH3 3)CH3-CH2-CH-CH2-CH3 Br Вя (1 bromopentane) ( 2-bromopentane) (3-bromapentane) Br © 4products Prev
