Question

Which hybrid orbitals are used by carbon atoms in the molecules ?

(a) = CH3CH2OH
(b) = CH3 - CH = CH2​

Answer 1

Explanation:

A) Both the carbons C1 & C2 are making single bond(sigma bond),therefore they are sp3hybridized.

B) Here C1 is making 4 sigma bond therefore it s sp3 hybridised , while C2 and C3 are making a double bond( 1 sigma + 1 pie bond ) therefore they both are sp2 hybridized.
