Chloroform can be obtained from:

Amethanal
B2-propanol
Correct Answer
Cmethanol
D1-propanol

Solution

Chloroform can be obtained from Propan-2-ol by haloform reaction which is given by methyl ketones or compounds which can be easily oxidized to methyl ketones.

$$\displaystyle CH_3CH(OH)CH_3 \xrightarrow [Cl_2, \: NaOH] {-H_2O, -NaBr} CH_3COONa + CHCl_3 $$
