Which of the compounds with molecular formula C5H10 yields acetone on ...
Answer:
To determine which compound with the molecular formula C5H10 yields acetone on ozonolysis, we need to analyze the structure and reactivity of each compound.
1. 3-methyl-1-butene:
- Structure: CH3-CH=C(CH3)-CH2-CH3
- This compound has a double bond in the middle of the carbon chain.
- Upon ozonolysis, the double bond will be cleaved, resulting in two fragments: CH3-CH2-CHO and CH3-CO-CH2-CH3.
- Acetone (CH3-CO-CH3) is not formed, so this compound does not yield acetone on ozonolysis.
2. Cyclopentane:
- Structure: C5H10 (cycloalkane)
- Cyclopentane does not have any double bonds or functional groups that can be cleaved by ozonolysis.
- Hence, cyclopentane does not yield acetone on ozonolysis.
3. 2-methyl-1-butene:
- Structure: CH3-CH=C(CH3)-CH2-CH3
- This compound has a double bond at the beginning of the carbon chain.
- Upon ozonolysis, the double bond will be cleaved, resulting in two fragments: CH3-CH2-C(O)H and CH3-CO-CH2-CH3.
- Acetone (CH3-CO-CH3) is formed, so this compound yields acetone on ozonolysis.
4. 2-methyl-2-butene:
- Structure: CH3-C(CH3)=C(CH3)-CH3
- This compound has a double bond at the end of the carbon chain.
- Upon ozonolysis, the double bond will be cleaved, resulting in two fragments: CH3-C(CH3)=CHO and CH3-CO-CH2-C(CH3)3.
- Acetone (CH3-CO-CH3) is not formed, so this compound does not yield acetone on ozonolysis.
Conclusion:
Among the given compounds, only 2-methyl-1-butene (option D) yields acetone on ozonolysis.
