What type of hybridization is/are present in Hex-4-ene 1-yne:
- A
Sp2
- B
Sp
- C
Sp and Sp2
- D
Sp. Sp2. Sp3
The first carbon atom has an sp hybridization, as it is involved in a triple bond with another carbon atom.
The second and third carbon atoms have sp2 hybridization, as they are involved in a double bond with a carbon atom and a single bond with two other carbon atoms.
The fourth carbon atom has sp hybridization, as it is involved in a triple bond with a carbon atom.
The fifth carbon atom has sp2 hybridization, as it is involved in a double bond with a carbon atom and a single bond with two other carbon atoms.
The sixth carbon atom has sp3 hybridization, as it is bonded to two other carbon atoms and two hydrogen atoms, resulting in a tetrahedral geometry.
Therefore, the correct answer is D) sp, sp2, sp, sp2, sp, sp3.
Explanation is given below.
