Question

2,3-dimethylpent-2-ene, (CH3)2C=C(CH3)CH2CH3, is treated with cold, dilute KMnO4. The product
of this reaction is treated with an excess of concentrated H2SO4 at 180 °C, giving a mixture of
isomeric hydrocarbons with molecular formula C7H12.
What is the name of one of the isomeric hydrocarbons?
A 2,3-dimethylpenta-1,2-diene
B cis-2,3-dimethylpenta-1,3-diene
C 2,3-dimethylpenta-1,4-diene
D 3,4-dimethylpenta-1,3-diene

Answer 1

Answer:

B cis-2,3-dimenthylpenta-1,4-diene
