Question

6. Which of the following compounds is an allylic halide?
a) 1 Chloropropane
b) 3 Chloropropene
c) 2 Chloropropene
d) 1 Chloropropene

Answer 1

chemical formula of an organic molecule Allyl chloride is made up of CH2=CHCH2Cl. Allyl chloride is a colourless, water-insoluble liquid that can be dissolved in various solvents.

• Because allyl chloride has a parent chain with three carbons and one double bond, the parent chain will be referred to as propene. According to IUPAC nomenclature, the double bond takes precedence over the chlorine atom in numbering.
• -
• 3-Chloroprop-1-ene is the IUPAC nomenclature for allyl chloride.

Answer 2

The following compounds which is an allylic halide is Option(d) 1 Chloropropene.

Explanation:-

• Allylic halides are the compounds in which the halogen atom is bonded to sp 3 −hybridised carbon atom next to carbon-carbon double bond (C=C).
• For example; CH3CH=CHCH2Cl is an allylic halide. Such halides are reactive in both Sn1 and Sn2 mechanisms.
