What is the approximate bond angle around the central carbon atom in acrolein?
Pavlova-9 [17]
Hello!

The approximate bond angle around the central carbon atom in acrolein is 120°

The structure of acrolein is shown in the figure below. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).

Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°. 

Have a nice day!
