What is the shielding effect of acetylenic protons?
Therefore acetylenic protons are shielded and experience lesser field strength and consequently resonate at smaller value of chemical shift. Carbonyl compound when placed in an external magnetic field is so oriented that the plane of the carbon-oxygen double bond is perpendicular to the applied field.
