Draw Structural and write condensed formula of Alkane , Alkene and Alkyne with their respective nomenclature.
Answers
Explanation:
Ethylene and acetylene are synonyms in the IUPAC nomenclature system for ethene and ethyne, respectively. Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons. The chain is numbered in the direction that gives the lowest number to the first multiply bonded carbon, and adding it as a prefix to the name. Once the chain is numbered with respect to the multiple bond, substituents attached to the parent chain are listed in alphabetical order and their positions identified by number.
Hydrocarbon. Structural formulas for 1-pentene, 2-methyl-2-hexene, and 7-methyl-3-octyne.
Compounds that contain two double bonds are classified as dienes, those with three as trienes, and so forth. Dienes are named by replacing the -ane suffix of the corresponding alkane by -adiene and identifying the positions of the double bonds by numerical locants. Dienes are classified as cumulated, conjugated, or isolated according to whether the double bonds constitute a C=C=C unit, a C=C―C=C unit, or a C=C―(CXY)n―C=C unit, respectively.
Hydrocarbon. examples of diene compounds: 2,3-pentadiene (cumulated), 1,3-pentadiene (conjugated), and 1,4-pentadiene (isolated).
Double bonds can be incorporated into rings of all sizes, resulting in cycloalkenes. In naming substituted derivatives of cycloalkenes, numbering begins at and continues through the double bond.
