Question

what is the difference between lower terminal alkyne and internal alkyne.​

Answer 1

Answer:

Explanation:

Internal alkynes feature carbon substituents on each acetylenic carbon. Symmetrical examples include diphenylacetylene and 3-hexyne. Terminal alkynes have the formula RC2H. An example is methylacetylene (propyne using IUPAC nomenclature).

Or we can say Internal alkynes, with its sp carbons attached to other carbons, will show weak bands for its triple bond at the 2100-2260 cm-1 region. ... Terminal alkynes, where the sp carbon is attached to a hydrogen, will show bands on the IR spectrum for both its alkynyl hydrogen and its triple bond
