Question

18. The hydrocarbon C3H6
must have
(a) all single bonds
(C) one triple bond
(b) one double bond
(d) two double bond
​

Answer 1

Answer:

option B is correct answer

Answer 2

The correct answer is option (b) One double bond.

• The hydrocarbons which contains carbon-carbon double bond are Alkenes.
• The general formula of Alkenes is CnH2n.
• So, when n=3 the hydrocarbon will be C₃H₆.
• So, the hydrocarbon C₃H₆ must have one double bond.
