Consider the following Lewis structure. (Lone pairs are not drawn in.) What are the hybridizations of the oxygen atom and of carbon atoms 1, 2, and 4, respectively (order: O C-1 C-2 C-4)? A) sp² sp³ sp² sp³ B) sp sp³ sp sp C) sp³ sp³ sp sp² D) sp sp² sp sp² E) sp sp³ sp² sp

- The oxygen atom has 2 electron domains (1 single bond and 2 lone pairs), so it is sp hybridized.
- Carbon atom 1 has 2 electron domains (1 single bond and 1 double bond), so it is sp hybridized.
- Carbon atom 2 has 3 electron domains (1 single bond, 1 double bond, and 1 lone pair), so it is sp2 hybridized.
- Carbon atom 4 has 2 electron domains (2 single bonds), so it is sp hybridized.

Therefore, the hybridizations are: 
O: sp
C-1: sp
C-2: sp2
C-4: sp
