Question

Answer

The chain contains three carbon atoms ..numbering is given starting from functional group which is aldehyde..and 3rd place comes to carbon containing 3 chlorine atoms..therefore the IUPAC name of the given compound is 3,3,3-Trichloropropanal

Answer

According to the IUPAC nomenclature we give preference to the functional group so no.  should be from right to left at 1st position CHO gp mean aldehyde give 'al'at last position 3C so propanal at 3rd position cl go is present so name is''3,3,3trichloropropanal

Answer

First prefarence goes to ALDEHYDE  so option A is correct

Answer

We should give first preference to the functional group added .As per this question naming should done from right side. Here functional group is aldehyde so the name of the compound ends with'al'
given,
Total number carbon atom is 3 so it is propane
on the third carbon three chlorine atom is attached so it would be 3,3,3trichloro...
Thus the name of the given compound is
3,3,3trichloropropanal

Answer

The IUPAC name of the compound having the molecular formula Cl₃C-CH₂CHO is 3,3,3-Trichloropropanal.

Explanation:
The given compound has a molecular formula of Cl₃C-CH₂CHO, which suggests that it is a derivative of propane with three chlorine atoms and an aldehyde group attached to the carbon chain.

Let's break down the IUPAC name step by step:

1. Identify the longest carbon chain:
In this case, the longest carbon chain is a three-carbon chain, so the parent chain is propane.

2. Number the carbon atoms in the chain:
The carbon atoms in the chain are numbered from left to right. The carbon atom attached to the aldehyde group is given the lowest number possible. In this case, the aldehyde group is attached to the second carbon atom. Therefore, the carbon atoms are numbered as follows:

CH₃-CH(-CHO)-CH₃
1 2 3

3. Name the substituents:
In this compound, there are three chlorine atoms attached to the first carbon atom. Since there are three chlorine atoms, the prefix 'trichloro' is used.

4. Combine the names of the substituents with the parent chain name:
The IUPAC name is obtained by combining the names of the substituents and the parent chain together. In this case, the name is 'trichloropropane.'

5. Indicate the functional group:
Since the compound contains an aldehyde group, it is named as an aldehyde. The suffix '-al' is added to the parent chain name.

6. Combine the functional group name with the parent chain name:
The IUPAC name is obtained by combining the functional group name with the parent chain name. In this case, the name is 'propanal.'

7. Combine all the names together:
Finally, the substituent name 'trichloro' is combined with the parent chain name 'propane' and the functional group name 'propanal.' The resulting IUPAC name is '3,3,3-Trichloropropanal.'

Therefore, the correct IUPAC name for the compound with the molecular formula Cl₃C-CH₂CHO is 3,3,3-Trichloropropanal.
