Concept explainers
Interpretation:
Given alkene whether has cis, trans isomerization has to be identified and if present, the structure of trans isomer has to be drawn
Concept Introduction:
- • Name the main chain: Find the longest carbon chain and name the chain according to the number of carbon atoms it contains; is also the suffix part of the name.
- • Number the carbon atoms in the main chain: The carbons are numbered, in which the substituents must get lowest possible numbers.
- • Identify the substituents, and number each: The number at where substituents are present has to be noted. The substituents written as prefix.
- • Write the names as a single word: Use the hyphen to separate the numbers from the different prefix; commas to separate numbers. If two or more different substituents are present, arrange them in alphabetical order. If two or more identical substituents are present, use prefixes di-, tri-, tetra-, but this particular prefix should not be used for alphabetizing purpose.
Alkene:
The systematic name of alkenes are written by replacing “ane” of
Trans configuration: In trans configuration, carbon atoms present in the main chain are placed on opposite sides of the carbon-carbon double bond.
Cis configuration: In cis configuration, carbon atoms present in the main chain are placed on same sides of the carbon-carbon double bond.
