WebThe sp3 C-H stretching vibrations are just to the right of 3000cm-1 and since it is an internal alkyne, there is no sp C-H near 3300cm-1. 3b. A terminal alkyne, hex-1-yne, HC≡CCH2CH2 CH2CH3. Note that the terminal alkyne is more polar and the C≡C is obvious (medium intensity, (near 2100cm-1).. Web4 Correct ways to Look at IR + Analyze: 1. From left to right 2. Look for both absence and presence 3. Ignore fingerprint regions 4. Draw a straight line at 3000 wavelengths Isopentylamine has two N-H peaks while N-butylacetamide has only one N-H peak. Why? a) Methylamine has a higher propensity to hydrogen bond compared to N-butylacetamide
