Benzylic position allylic position propargylic.
Three vinylic hydrogens.
Please explain what is vinylic and allylic.
Allylic carbon can have a maximum of 3 hydrogen atoms.
Vinylic c h bond is lower.
However hydrogens of external alkynes resonate at lower frequency than vinylic hydrogens at appear at 2 3 ppm range.
A hydrogen atom bonded to an sp 2 carbon of an alkene.
The reason is that unlike alkenes the induced magnetic field of the p electrons in the triple bond is opposite to the applied magnetic field.
We also acknowledge previous national science foundation support under grant numbers 1246120 1525057 and 1413739.
C three vinylic hydrogens and ane allylic hydrogens.
Allylic carbon only forms a single bond.
Vinylic carbon can have only two carbon as the maximum number.
None of the other hydrogens are vinylic.
Number of hydrogen atoms.

Give the structures of a hydrocarbon that has six carbon atoms and a three vinylic hydrogens and two allylic hydrogens b three vinylic hydrogens and no allylic hydrogens.
This puts the proton in a shielded environment and thus it feels a weaker magnetic.
