II. Read the following passage and answer questions 6-10 that follow :
During organic reactions, a covalent bond between two carbon atoms or carbon atom and some other atom is broken and a new bond is formed. The fission of bonds can be homolytic or heterolytic forming free radicals, carbocations carbanions, carbenes, etc. This also depends upon the displacement, of electron in a bond and is governed by inductive effect, electromeric effect, reasonance and hyperconjugation.
Which of the two `CH_2 = CH^(-)` or `HC -= C^(-)` is a better nucleophile?

Text Solution

AI Generated Solution

To determine which of the two species, `CH2=CH^(-)` or `HC≡C^(-)`, is a better nucleophile, we need to analyze their structures and the characteristics of their respective carbon atoms. ### Step-by-Step Solution: 1. **Identify the Hybridization of Carbon Atoms**: - In `CH2=CH^(-)`, the carbon atoms involved in the double bond (C=C) are sp² hybridized. The carbon with the negative charge (C^(-)) is also sp² hybridized. - In `HC≡C^(-)`, both carbon atoms are involved in a triple bond (C≡C), which means they are sp hybridized. ...
