In allene ($C_{3}H_{4}$), the type(s) of hybridization of the carbon atoms, is(are)

Answer:

Explanation:

Allete is the name given to propdiene,

$H_{2}C=C=CH_{2}$

The hybridization of an atom is determined by determining the number of hybrids orbitals ar that atom which is equal to the number of sigma ($\sigma$)  bonds plus a number of lone pairs at the concerned atom.

Here, the terminal carbons have only three sigma bonds associated with them, therefore, hybridization of terminal carbons is sp³. The central carbon has only two sigma bonds associated, hence hybridization at central carbon is sp
