Infra-red absorption ranges for some bonds are as follows:

C-H, 2850 - 3300 cm-1

C=C, 1620 - 1680 cm-1

C=O, 1680 - 1750 cm-1

C-O, 1000 - 1300 cm-1

O-H (alcohols), 3230 - 3550 cm-1

O-H (acids), 2500 - 3000 cm-1

The IR spectrum of propanal has one particularly strong absorption peak

This can be expected to be at:

4 / 10

The peak with the largest mass to charge ratio in the mass spectrum of an alkane is detected at mass-to-charge ratio = 58.

This shows that the hydrocarbon:

5 / 10

Species such as CH3+ and Br+ can be detected in a mass spectrum but do not occur in chemical reactions under typical laboratory conditions.

This is because in a mass spectrometer:

This procedure produces a white precipitate which dissolves easily in dilute ammonia solution: heating C4H9X for a few minutes with aqueous alkali, then acidifying the mixture with dilute nitric acid and adding silver nitrate. This shows that X is:

7 / 10

Heating butan-1-ol with a mixture of sodium bromide and concentrated sulfuric acid produces 1-bromobutane. During the preparation the reaction mixture turns orange due to the formation of:

8 / 10

What is the formula of 2-bromo-3-methylpentane?

9 / 10

What is the product when methanol and propanoic acid are mixed and warmed in the presence of a few drops of acid?
