What type of hybridization does the central carbon in allenes have?
What type of hybridization does the central carbon in allenes have?
- sp3 hybridization
- dsp2 hybridization
- sp hybridization (correct)
- sp2 hybridization
When are allenes chiral?
When are allenes chiral?
- When they have an odd number of cumulated double bonds and the terminal carbons of the axis are attached to different atoms
- When they have an even number of cumulated double bonds and the terminal carbons of the axis are attached to different atoms (correct)
- When they have an odd number of cumulated double bonds and the terminal carbons of the axis are attached to the same atoms
- When they have an even number of cumulated double bonds and the terminal carbons of the axis are attached to the same atoms
Why are allenes not planar?
Why are allenes not planar?
- Due to the conjugation of double bonds
- Due to the presence of sp3 hybridization in the central carbon
- Due to the absence of pi-bonds
- Due to the fact that the two pi-bonds of allene are at right angles to each other (correct)
