Polarization of electrons in acrolein may be written as:
Options
- AC - δ H 2 = CH - C + δ = O
- BC - δ H 2 = CH - CH = O + δ
- CC - δ H 2 = C + δ H - CH = O
- DC + δ H 2 = CH - CH = O - δ
Correct answer
D. C + δ H 2 = CH - CH = O - δ
Step-by-step solution
O atom is more electronegative than C atom, so it acquires - δ charge and C atom acquires + δ charge which is transferred to the last C atom.
