Question

In phenol, what is the hybridization of carbon atom attached to -OH group?​

Answer 1

your answer is above in the image

Answer 2

Answer:

Steric Number = Number of atoms bonded to atom + Number of lone pairs attached to the atom. 

If the steric number is 2, the atom is sp

If the steric number is 3, the atom is sp2

If the steric number is 4, the atom is sp3

For carboxylic acid, R−COOH two oxygen atoms and R group are bonded to the carbonyl carbon.  There are no lone pairs attached to the carbonyl carbon. 

∴ Steric number =3 (No. of atoms bonded to carbonyl carbon) +0 (No. of lone pairs bonded to carbonyl carbon) =3 

Therefore, the carbon atom is sp2 hybridized
