Detailed explanation-1: -Alkenes are unsaturated hydrocarbons and the number of hydrogen atoms is twice that of carbon atoms i.e. CnH2n.
Detailed explanation-2: -Hydrocarbons having at least one triple bond between two carbon atoms are known as alkyne. General formula of alkyne is CnH2n−2. As in case of alkene, minimum two carbon atoms are required to form alkyne.
Detailed explanation-3: -Alkenes are defined as either branched or unbranched hydrocarbons that possess at least one carbon–carbon double bond (CC) and have a general formula of CnH2n [1].
Detailed explanation-4: -The general molecular formula of alkane for straight and branched-chain alkanes is CnH2n+2 and that of cyclic alkanes is CnH2n. For example in the diagram, the four hydrocarbon molecules contain 8 carbon atoms each.
Detailed explanation-5: -The general formula of alkene is CnH2n If 2n=10; then n=5 and so formula is C5H10. The molecular formula of alkene when there are 10 H atoms in it C5H10 (pentene).
