An alkyne has seventy-five carbon atoms in its molecule. The number of hydrogen atoms in its molecule will be: A. 150 B. 148
C. 152
D. 146

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. Here, n is number of carbon atoms. If number of carbon atoms (n)=75 Then, CnH2n-2 = C75H75X2-2 =C75H148 The number of hydrogen atoms is 148.
