Question

In the nomenclature of alkenes, if a substituent, double bond and triple bond all are present in the structure and both multiple bonds are at the same distance from substituent then:

• A. the double bond is preferred over triple bond
• B. the triple bond is preferred over double bond
• C. the substituent is preferred over multiple bonds
• D. none of these

Answer 1

The correct option is A the double bond is preferred over triple bond

In the IUPAC nomenclature of alkenes, if a substituent, double bond and triple bond all are present in the structure and both multiple bonds are at the same distance from substituents then the double bond is preferred over triple bond as in order of priority of functional groups alkenes come first over alkynes.
