As compared to pure atomic orbitals,hybrid orbitals have

When the hybridisation state of a carbon atom changes from $sp^3$ to $sp^2$ to $sp$,the angle between the hybridised orbitals

How many $sp^2$ and $sp$ hybridized carbon atoms are present respectively in the following compound? (The structure is $1,2-didehydrobenzene$ or $benzyne$ derivative,specifically $1,2-didehydrocyclohexadiene$ structure shown in the image).

Chlorine atom,in its third excited state,reacts with fluorine to form a compound $X$. The formula and shape of $X$ are :

The hybridisation of the central atom in $NF_3$ is:

What is the $s$-character content in an $sp^3$ hybrid orbital?
