Question

Add hydrogen atoms to each of the hydrocarbons and identify the class of molecule to which each belongs. Add hydrogen atoms to the first hydrocarbon. 

Answer 1

Part (1):- The given molecule is hydrocarbon molecule because it contain only carbon and hydrogen. The first hydrocarbon contains triple bond as a functional group which represents an alkyne family of the hydrocarbon. So, the first hydrocarbon is and Alkyne. Then the structure of the given hydrocarbon with addition of the hydrogen atoms is given as below:-

ннн н-c-c=C-с-с-н н н-с-НН 4-methylpent-2-yne

Part (2):- The given molecule is a hydrocarbon molecule because it contain only carbon and hydrogen. The second hydrocarbon contains double bond as a functional group which represents an alkene family of the hydrocarbon. So, the second hydrocarbon is and Alkene. Then the structure of the given hydrocarbon with addition of the hydrogen atoms is given as below:-

н н н н Ін-с-Hн н— c — c— c— c | н н. H-C-H — c —н н О-І 4-methylhex-1-ene
