Chemistry Question on Polymers
A hydrocarbon has molecular formula C2H6. Which of the class of hydrocarbons cannot have this formula?
A
(A) Cycloalkene
B
(B) Bicycloalkane
C
(C) A diene
D
(D) None of these
Answer
(D) None of these
Explanation
Solution
Explanation:
A bicycloalkene cannot have the formula of C2H6.C2H6 has two degree of unsaturation (two H2 less than saturated hydrocarbons), therefore it can be a diene, a cycloalkene or a bicycloalkane but it cannot be a bicycloalkene because it has three degrees of unsaturation.Hence, the correct option is (D).
