which of the following have dipole-moment greater than that of propanal? explain.
acetone , butanone, acrolein, acetophenone, ethyl chloride, ethanal, methanal, mesityl oxide

Question

anonymous · Answer

I think ethanal,methanal are more.
This is because partial positive on carbonyl carbon is less  because CH3CH2CH2 has more +I than ethyl which is more than methyl. More +ve charge more dipole.

the answer key had 5 of them

anonymous · Answer

What is mesityl oxide?

anonymous · Answer

I'm actually not sure of the two i've written either, you should consult somebody else.

anonymous · Answer

acetophenone also will have more i think as Ph donated electrons through resonance.

anonymous · Answer

4-methylpent-3-en-2-one    is mesityl oxide

anonymous · Answer

This would also be more than propanal as there is resonance which increases dipole(It makes Oxygen negative increasing dipole)
