No. of structural isomers possible in C3H6O are 1)9 2)6 3)5 4)3?
The number of structural isomers possible in C3H6O can be determined by analyzing the different ways the atoms can be arranged within the molecule.

Determining the molecular formula:
C3H6O represents a molecular formula with 3 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom.

Identifying the possible isomers:
To determine the possible structural isomers, we need to consider the different ways the atoms can be arranged within the molecule while maintaining the same molecular formula.

1. Straight chain aldehyde:
The simplest isomer is a straight chain aldehyde, which has the functional group -CHO. In this case, the carbon chain contains three carbon atoms with the aldehyde group attached to one end.

2. Straight chain ketone:
Another isomer is a straight chain ketone, which has the functional group -C=O. In this case, the carbon chain contains three carbon atoms with the carbonyl group attached to the middle carbon atom.

3. Branched aldehyde:
A branched aldehyde is an isomer where the carbon chain has a branch, and the aldehyde group is attached to one of the carbon atoms in the branch. There are two possible positions for the aldehyde group: at the end of the main chain or at the end of the branch.

4. Branched ketone:
A branched ketone is an isomer where the carbon chain has a branch, and the carbonyl group is attached to one of the carbon atoms in the branch. There are two possible positions for the carbonyl group: in the middle of the main chain or in the middle of the branch.

5. Cyclic ketone:
A cyclic ketone is an isomer where the carbon atoms form a ring, and the carbonyl group is attached to one of the carbon atoms in the ring. In this case, the carbon chain contains three carbon atoms, and the carbonyl group is attached to one of the end carbon atoms.

Calculating the total number of isomers:
To calculate the total number of isomers, we sum up the number of isomers from each category:

1 straight chain aldehyde + 1 straight chain ketone + 2 branched aldehydes + 2 branched ketones + 1 cyclic ketone = 7 isomers

Therefore, the correct answer is 7, which is not listed among the given options.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The existence of coordination compounds with the same formula but different arrangements of the ligands was crucial in the development of coordination chemistry. Two or more compounds with the same formula but different arrangements of the atoms are called isomers. Isomers are compounds with the same molecular formula but different structural formulas and do not necessarily share similar properties. There are many different classes of isomers, like stereoisomers, enantiomers, and geometrical isomers. There are two main forms of isomerism: structural isomerism and stereoisomerism. The different chemical formulas in structural isomers are caused either by a difference in what ligands are bonded to the central atoms or how the individual ligands are bonded to the central atoms.The following questions are multiple choice questions. Choose the most appropriate answer:Q. What kind of isomerism exists between [Cr(H2O)6]Cl3 (violet) and [Cr(H2O)5Cl]Cl2.H2O (greyish green)?
