Organic Chemistry: Techniques & Spectra (Edexcel International A Level Chemistry)

In a mass spectrum, the molecular ion is the ion which always has the

Butan-1-ol and butan-2-ol are isomers.

Which m / z value would be expected to have a significant peak in the mass spectrum of butan-1-ol but not that of butan-2-ol?

Which could be the infrared spectrum of CH₂=CHCH₂OH?

An aliphatic organic compound has the infrared spectrum shown.

What are the bond stretches responsible for the peaks P and Q in the spectrum?

		P	Q
□	A	O—H carboxylic acid	CO carboxylic acid
□	B	O—H carboxylic acid	CO aldehyde
□	C	C—H aldehyde	CO carboxylic acid
□	D	C—H aldehyde	CO aldehyde
