Question:
HC $=$ C$^{-}$ is more stable than HC $=$ CH$^{-}$.
HC $=$ C$^{-}$ has more s-character than HC $=$ CH$^{-}$.

- If both assertion and reason are true and reason is the correct explanation of assertion
- If both assertion and reason are true but reason is not the correct explanation of assertion
- If assertion is true but reason is false
- If both assertion and reason are false
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
HC $=$ C$^{-}$ has 50% s-character and HC $=$ CH$^{-}$ has 33% s-character. Stability of carbanions increases with an increase in the s-character at the carbanion. So HC $=$ C$^{-}$ is more stable than HC $=$ CH$^{-}$.

Concepts Used:
Hydrocarbons
Hydrocarbons can be described as organic compounds that consists only hydrogen and carbon atoms. These compounds are of different types and thereby have distinct natures. Hydrocarbons are colorless gases and are known for discharging faint odours. These have been categorized under four major classes named as alkynes, alkanes, alkenes, and aromatic hydrocarbons.
Types of Hydrocarbons
- Saturated hydrocarbons - Saturated hydrocarbons are those compounds where there is a single bond exists between carbon atoms and are saturated with atoms of hydrogen.
- Unsaturated hydrocarbons - Hydrocarbons comprises of at least one double or triple bond between carbon atoms are known as unsaturated hydrocarbons.
- Aliphatic hydrocarbons - The term denotes the hydrocarbons formed as an outcome of the chemical degradation of fats. Aliphatic hydrocarbons are basically chemical compounds.
- Aromatic hydrocarbons - They are distinguished because of the presence of benzene rings in them. They give away distinct types of aroma. These hydrocarbons comprises of only hydrogen and carbon atoms.
