A compound with molecular formula C4H8O has a strong absorption …

WebAlkynes have characteristic IR absorbance peaks in the range of 2100-2250 cm -1 due to stretching of the carbon-carbon triple bond, and terminal alkenes can be identified by their absorbance at about 3300 cm-1, due to stretching of the bond between the sp-hybridized carbon and the terminal hydrogen. WebThe IR spectrum shows a strong absorption at 1725 cm-1 – indicating a ketone, aldehyde or carboxylic acid carbonyl. The peaks at 2850 and 2750 cm-1 confirm that the molecule contains an aldehyde. The parent ion is 72, and the M+1 peak is about 6% of the parent ion. Subtracting one oxygen atom (for the carbonyl) from 72 leaves us with 56. reloaded 223 ammo
