Q. 544.2( 5 Votes )

A hydrocarbon having one double bond has 100 carbon atoms in its molecule. The number of hydrogen atoms in its molecule will be: A. 200 B. 198
C. 202
D. 196

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 4. Carbon and Its Compounds

Answer :

Hydrocarbons having at least one double bond between two carbon atoms are called alkenes. The general formula of alkenes is CnH2n. Here, n is number of carbon atoms. If number of carbon atom is (n)=100 Then, CnH2n=C100H200
