Carbon atoms in diamond are bonded to each other in a configuration:

The hybridization in methane,ethene and ethyne respectively is

Which of the following molecules has unequal bond lengths?

The bond angle between two hybrid orbitals is $105^{o}$. The $\%$ $s-$orbital character of the hybrid orbital is:

The outer orbitals of $C$ in ethene molecule can be considered to be hybridized to give three equivalent $sp^2$ orbitals. The total number of sigma $(\sigma)$ and pi $(\pi)$ bonds in ethene molecule is

Compare the carbon-carbon $\sigma$ bond length in ethane, ethylene and acetylene.
