Haloalkanes
Haloalkanes are a class of organic compounds that contain one or more halogen atoms (such as fluorine, chlorine, bromine, or iodine) attached to a carbon atom in a hydrocarbon chain. The halogen atom(s) are attached to the sp3 hybridized carbon atom(s) of an alkyl group.
Identifying Haloalkane Compounds
To identify the haloalkane compounds from the given options, we need to examine the structure of each compound and determine if it meets the criteria of having a halogen atom attached to an sp3 hybridized carbon atom.
(i) 2-bromopentane
- This compound is named as 2-bromopentane, indicating that it is a pentane molecule with a bromine atom attached at the second carbon atom.
- Pentane is an alkane, and the presence of the bromine atom makes it a haloalkane.
- Therefore, 2-bromopentane is a haloalkane.
(ii) Vinyl Chloride (Chloroethane)
- This compound is named as vinyl chloride or chloroethane, indicating that it is an ethane molecule with a chlorine atom attached to one of the carbon atoms.
- Ethane is an alkane, and the presence of the chlorine atom makes it a haloalkane.
- Therefore, vinyl chloride or chloroethane is a haloalkane.
(iii) 2-Chloroacetophenone
- This compound is named as 2-chloroacetophenone, indicating that it is a derivative of acetophenone with a chlorine atom attached at the second carbon atom.
- Acetophenone is not an alkane, but rather a ketone compound.
- Although it contains a chlorine atom, it is not attached to an sp3 hybridized carbon atom of an alkyl group.
- Therefore, 2-chloroacetophenone is not a haloalkane.
(iv) Trichloromethane
- This compound is named as trichloromethane, which is another name for chloroform.
- Chloroform has three chlorine atoms attached to a single carbon atom.
- The carbon atom is sp3 hybridized and is part of an alkyl group.
- Therefore, trichloromethane is a haloalkane.
Correct Answer
From the given compounds, only 2-bromopentane (i) and trichloromethane (iv) meet the criteria of being haloalkanes. Therefore, the correct answer is option 'C' (i.e., (i) and (iv)).
Haloalkanes are a class of organic compounds that contain one or more halogen atoms (such as fluorine, chlorine, bromine, or iodine) attached to a carbon atom in a hydrocarbon chain. The halogen atom(s) are attached to the sp3 hybridized carbon atom(s) of an alkyl group.

(i) 2-bromopentane
- This compound is named as 2-bromopentane, indicating that it is a pentane molecule with a bromine atom attached at the second carbon atom.
- Pentane is an alkane, and the presence of the bromine atom makes it a haloalkane.
- Therefore, 2-bromopentane is a haloalkane.
(ii) Vinyl Chloride (Chloroethane)
- This compound is named as vinyl chloride or chloroethane, indicating that it is an ethane molecule with a chlorine atom attached to one of the carbon atoms.
- Ethane is an alkane, and the presence of the chlorine atom makes it a haloalkane.
- Therefore, vinyl chloride or chloroethane is a haloalkane.
(iii) 2-Chloroacetophenone
- This compound is named as 2-chloroacetophenone, indicating that it is a derivative of acetophenone with a chlorine atom attached at the second carbon atom.
- Acetophenone is not an alkane, but rather a ketone compound.
- Although it contains a chlorine atom, it is not attached to an sp3 hybridized carbon atom of an alkyl group.
- Therefore, 2-chloroacetophenone is not a haloalkane.
(iv) Trichloromethane
- This compound is named as trichloromethane, which is another name for chloroform.
- Chloroform has three chlorine atoms attached to a single carbon atom.
- The carbon atom is sp3 hybridized and is part of an alkyl group.
- Therefore, trichloromethane is a haloalkane.
Correct Answer
From the given compounds, only 2-bromopentane (i) and trichloromethane (iv) meet the criteria of being haloalkanes. Therefore, the correct answer is option 'C' (i.e., (i) and (iv)).
