JEE Mains · Chemistry · STD 11 - 8.4. Organic chemistry reaction mechanism
The correct order for acid strength of compounds \(CH \equiv CH,\,C{H_3} - C \equiv CH,\,C{H_2} = C{H_2}\) is as follows
- A \(CH \equiv CH > C{H_2} = C{H_2} > C{H_3} - C \equiv CH\)
- B \(C{H_3} - C \equiv CH > CH \equiv CH > C{H_2} = C{H_2}\)
- C \(C{H_3} - C \equiv CH > C{H_2} = C{H_2} > CH \equiv CH\)
- D \(CH \equiv CH > \,C{H_3} - C \equiv CH > \,C{H_2} = C{H_2}\)
