A) partially free state
B) not in free state
C) free state
D) None of the above
Correct Answer: B
Solution :
Alkynes are unsaturated hydrocarbons containing a \[C\equiv C\] bond. Their general formula is \[{{C}_{n}}{{H}_{2n-2}}\]. Alkynes are very reactive. So, they do not occur in nature in free state. The carbon-carbon triple bond is made up of two weak Ti-bonds and one strong or-bond. Note - The carbon atoms forming a triple bond are sp-hybridized.
