The shape of a carbocation is:

Arrange the $(C-H)$ bonds $x, y$ and $z$ in decreasing order of their bond dissociation energies in homolysis.

What is homolytic cleavage of a covalent bond? Explain with an example. Or,write about bond cleavage and the intermediate free radical.

The number of hyperconjugation structures involved to stabilize the carbocation formed in the above reaction is $.............$.

For the following bond cleavages,use curved-arrows to show the electron flow and classify each as homolysis or heterolysis. Identify the reactive intermediate produced as free radical,carbocation,or carbanion.

Which of the following carbanions is the most stable?
