Question

Which hybrid orbitals are used by carbon atoms in the following molecules ? (a) CH 3 –CH 3 (b) CH 3 –CH=CH 2 (c) CH 3 -CH 2 -OH (d) CH 3 -CHO (e) CH 3 COOH

Answer 1

(a)CH 3 −CH3

Both the carbon atoms are sp3hybridized.

(b)CCH3 −CH=CH2

The carbon atom of methyl group is sp3 hybridized whereas other two carbon atoms are sp2hybridized.

(c)CCH3 −CH2−OH

Both the carbon atoms are sp3hybridized.

(d)Cc2 −CHO

The carbon atom of methyl group is sp3hybridized whereas the other carbon atom is sp2 hybridized.

(e)CH3COOH

The carbon atom of methyl group is sp3hybridized whereas the other carbon atom is s2
