Naphthalene
1,2-propadiene
toluene
1-phenyl ethylene​

Answer 1

Answer:

napthelene,.

thnks follow me ♥️♥️♥️

Answer 2

The following has all the C atoms as sp2 hybrid carbon atoms in it :

(a) Naphthalene

(d) 1-phenyl ethylene

- In naphthalene molecule, all the carbon atoms are sp2 hybridised.

​- In 1,2-propadiene molecule, the central carbon atoms is sp hybridised.

- In toluene molecule, the carbon atom of methyl group is sp3 hybridised.

- In 1-phenyl ethylene (i.e., styrene) molecule, all the carbon atoms are sp2 hybridised.

- Hence, the correct answers are Naphthalene and 1-phenyl ethylene​
