What temperature does propanone freeze?
The freezing point of propanone is -94,7 oC.
How many atom are in propanone?
Acetone (propanone) is (CH3)2CO so 10.
Which molecule has polar bond but its overall dipole momen is zero?
Symmetric molecules have no dipole moment. An example is carbon tetrachloride, CCl4 , which has no dipole moment yet the C-Cl bonds are polar, (chlorine is more electronegative than carbon). The chlorine atoms each have a small negative charge but because the molecule is tetrahedral there is no dipole and therefore no dipole moment
Which of these molecules has an overall dipole mome?
An overall dipole moment is H2S.
How do you find out whether an atom has a dipole dipole moment?
The more polar the molecule, the stronger the force.
Why does propanone has a higher boiling point than ethoxyethane?
Ethoxyethane is heavier than propanone and that will surely make a difference. The carbon-oxygen bond in ethers is less polarized than that in aldehydes and ketones. This is because the oxygen in ethers is attached to two electron pushing alkyl groups which account for the oxygen atom's electronegativity. Thus, dipole-dipole interactions are weaker in ethers giving them a lower boiling point than the corresponding aldehyde or ketone.
What molecule has an overall dipole moment?
All polar molecules have a permanent dipole moment, but London dispersion forces in non-polar molecules can cause temporary dipole moments as well.
What determines whether a molcule has an overall dipole moment?
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
What are the conditions for ammonia molecule to be IR active?
An IR Active stretch simply means that the vibrations of the molecule result in an overall dipole of the molecule. If a stretch has a dipole, it is IR active. If a stretch does not have a dipole. then it is IR Inactive.
What temperature does propanone freeze?
The freezing point of propanone is -94,7 oC.
Which pair of bonded atoms has the largest dipole moment?
c-f
Is propanone same as acetone?
Yes, propanone is acetone for all practical purposes.
How many atom are in propanone?
Acetone (propanone) is (CH3)2CO so 10.

Is propanone an alcohol?
no
What happens when propanone is reduced?
You usually reduce a ketone such as propanone using sodium borohydride to propanol.
Which of these molecules has an overall dipole mome?
An overall dipole moment is H2S.
