Q. Pick out the correct statement from the following and choose the correct answer from the codes given below Hexa-1, 5-diene is a conjugated diene Prop-1, 2-diene is conjugated diene Hexa-1, 3-diene is a conjugated diene Buta-1, 3-diene is an isolated diene Prop-1, 2-diene is a cumulative diene
A) I,II
B) II, III
C) IV, V
D) II, V
Explanation
(c)
In conjugated diene alternate single and double bonds are present while in cumulative diene, double bonds are present at adjacent positions.
[image:12_image502.emf]
$\Rightarrow \ \$It is an isolated diene.
[image:12_image503.emf]
$\Rightarrow \ \$It is a cumulative diene.
[image:12_image504.emf]
$\Rightarrow \ \$It is a conjugated diene.
[image:12_image505.emf]
$\Rightarrow \ \$It is a conjugated diene.
V. Prop -1, 2-diene is a cumulative diene.
Hence, statement 3 and 5 are correct.
