Concept explainers
(a)
Interpretation:
The chemical formula for carvone is to be discussed.
Concept introduction:
The chemical formula is the chemical composition of the compounds. It tells about the number and ratio of different atoms present in the given compound.
(b)
Interpretation:
The chiral carbon atom of carvone is to be discussed.
Concept introduction:
The Chiral Centre is an atom, in any compound at which there are four different groups connected to it in such a manner that its mirror image is non-superimposable on it.
(c)
Interpretation:
The aromaticity of carvone is to be discussed.
Concept introduction:
Aromaticity is defined as a property of cyclic, planar structure having ring of resonance bonds along with same set of atoms. The molecule is
