Q. 464.2( 5 Votes )
An unsaturated hydrocarbon having a triple covalent bond has 50 hydrogen atoms in its molecule will be: A. 24
B. 25
C. 26
D. 28
Answer :
Those unsaturated hydrocarbons which have one or more triple bonds along with the single bonds are called alkynes. The general formula of alkynes is CnH2n-2. For example, if an unsaturated hydrocarbon has 50 hydrogen atoms in its molecule, then number of carbon atom in its molecule will be 26. C26H26X2-2 = C26H50
