The number of isomers of C5H10isa)10b)11c)12d)13Correct answer is option 'D'. Can you explain this answer?

Question

Answer

Correct Answer :- d

Explanation : Given molecular formula is C₅H₁₀.

⇒ There are 6 isomeric alkenes by including Cis/trans isomers of pent−2−ene.

⇒ 7 Cycloalkanes also possible.

Totally it have 13 isomers.

Answer

There are six isomeric alkenes including the cis/ trans. Isomers of pent-2- ene. There are total 13 isomers with the molecular formula of C5H10.
So option ' D ' is correct answer.

Answer

There are different types of isomers that can be formed by a compound. Isomers are molecules that have the same molecular formula but differ in their structural arrangement or spatial orientation. In this case, we are looking at the isomers of C5H10, a hydrocarbon with five carbon atoms and ten hydrogen atoms.

To determine the number of isomers, we need to consider the different possibilities of arranging the carbon atoms and forming different structures.

1. Straight chain isomers:
The simplest arrangement of carbon atoms is in a straight chain. In this case, we can have a straight chain with five carbon atoms, which is called pentane. This is one isomer.

2. Branched chain isomers:
We can also have branched chain isomers by arranging the carbon atoms in different ways. Let's consider the possibilities:

- A carbon atom can have up to four bonds. If we consider branching from the second carbon atom onwards, we have the following options:
- The second carbon atom can form a branch with the third carbon atom. This gives us one isomer.
- The second carbon atom can form a branch with the fourth carbon atom. This gives us one isomer.
- The second carbon atom can form a branch with the fifth carbon atom. This gives us one isomer.

- If we consider branching from the third carbon atom onwards, we have the following options:
- The third carbon atom can form a branch with the fourth carbon atom. This gives us one isomer.
- The third carbon atom can form a branch with the fifth carbon atom. This gives us one isomer.

3. Cycloalkane isomers:
We can also form cycloalkane isomers by forming a ring structure with the carbon atoms. In this case, we can have a cyclopentane ring, which is another isomer.

4. Conformational isomers:
Lastly, we need to consider conformational isomers, which are different spatial arrangements of the same molecule. In the case of C5H10, there are no conformational isomers since the molecule does not have any rotatable bonds.

Adding up the isomers:
Adding up all the possibilities, we have:
- 1 straight chain isomer
- 3 branched chain isomers
- 1 cycloalkane isomer

Therefore, the total number of isomers of C5H10 is 1 + 3 + 1 = 5.

However, the correct answer is given as 13. This suggests that there are additional isomers that were not considered in the above analysis. These additional isomers may include structural isomers with different connectivity of atoms or stereoisomers with different spatial arrangements. Without further information, it is not possible to determine the exact nature of these additional isomers, but based on the given options, the correct answer is option D, 13 isomers.

It is important to note that the answer may vary depending on the specific conditions and constraints of the problem.
