An organic compound X on treatment with pyridinium chlorochromate in ...
Compound Y must give an iodoform test. Further since Y is obtained by the oxidation of X which must be an alcohol (CH3CH2OH) and thus Y is CH3CHO.
An organic compound X on treatment with pyridinium chlorochromate in ...
The given question involves the reaction of an organic compound X with pyridinium chlorochromate (PCC) in dichloromethane to form compound AND. The compound Y, obtained from AND, reacts with iodine (I2) and alkali to produce triiodomethane (CHI3). We need to identify the compound X from the given options.
1. Reaction of X with PCC in Dichloromethane
The reaction of compound X with pyridinium chlorochromate in dichloromethane (CH2Cl2) is a common oxidation reaction. PCC is a mild oxidizing agent that converts primary alcohols to aldehydes and secondary alcohols to ketones. This reaction involves the transfer of oxygen from the PCC to the alcohol group in compound X.
2. Formation of Compound AND
The reaction of X with PCC leads to the formation of compound AND. Since the given options are organic compounds, we can deduce that X is an alcohol. The oxidation of an alcohol results in the formation of a carbonyl compound. Among the given options, the only compound that can be oxidized to form a carbonyl compound is ethanol (C2H5OH).
3. Reaction of Y with I2 and Alkali
Compound Y obtained from AND reacts with iodine (I2) and alkali to form triiodomethane (CHI3). This reaction is known as the iodoform test, which is used to detect the presence of a methyl ketone or a compound that can be converted to a methyl ketone.
4. Identification of Compound X
From the given options, only ethanol (C2H5OH) can undergo oxidation to form a carbonyl compound (aldehyde). Therefore, the correct answer is option 'A' (C2H5OH).
In summary, the organic compound X in the given question is ethanol (C2H5OH). When treated with pyridinium chlorochromate (PCC) in dichloromethane, it forms compound AND. Compound Y, obtained from AND, reacts with iodine (I2) and alkali to produce triiodomethane (CHI3).
