To change:
The old name 2, 5, 5-trimethyl-2-hexene to the new, post-1993 name and to give its structure.
b) 2, 3-Dimethyl-1, 3-cyclohexadiene
Interpretation:
The old name 2, 3-dimethyl-1, 3-cyclohexadiene is to be changed to new, post-1993 name and its structure is to be given.
Concept introduction:
In 1993, The IUPAC changed its recommendations in naming the alkenes. As per the recommendations, the number indicating the position of double bond should be placed immediately before the – ene suffix instead of before the parent name.
