(1987, 1M)

Show Answer

Answer:

Correct Answer: 20. (b)

Solution:

Allene is the name given to propdiene, $H_{2} C = C = C H_{2}$

Hybridisation of an atom is determined by determining the number of hybrid orbitals at that atom which is equal to the number of sigma $(σ)$ bonds plus number of lone pairs at the concerned atom.

$Pi (π)$ bonds are not formed by hybrid orbitals, therefore, not counted for hybridisation.

Here, the terminal carbons have only three sigma bonds associated with them, therefore, hybridisation of terminal carbons is $s p^{3}$ . The central carbon has only two sigma bonds associated, hence hybridisation at central carbon is $s p$ .
