The correct order of acidity among the following is:
1. | \(\mathrm{CH \equiv CH > CH_3 - C \equiv CH }\) \(\mathrm{ > CH_2 = CH_2 > CH_3 - CH_3}\) |
2. | \(\mathrm{CH \equiv CH > CH_2 = CH_2 }\) \(\mathrm{ > CH_3 - C \equiv CH > CH_3 - CH_3}\) |
3. | \(\mathrm{CH_3 - CH_3 > CH_2 = CH_2 }\) \(\mathrm{ > CH_3 - C \equiv CH > CH \equiv CH }\) |
4. | \(\mathrm{ CH_2 = CH_2 > CH_3 - CH_3 }\) \(\mathrm{ > CH_3 - C \equiv CH > CH \equiv CH}\) |
undergoes Wurtz reaction to give-
1. | Propane + Ethane | 2. | Propane |
3. | Propane + Ethane + Butane | 4. | Propane + Butane |
The correct statement regarding the comparison of staggered and eclipsed conformations of ethane is:
1. | The eclipsed conformation of ethane is more stable than staggered conformation because eclipsed conformation has no torsional strain. |
2. | The eclipsed conformation of ethane is more stable than staggered conformation even though the eclipsed conformation has a torsional strain. |
3. | The staggered conformation of ethane is more stable than eclipsed conformation because staggered conformation has no torsional strain. |
4. | The staggered conformation of ethane is less stable than eclipsed conformation because staggered conformation has a torsional strain. |
