There are four total covalent bonds in H2CO. There is a single double bond between the oxygen and the carbon and two single bonds between the carbon and hydrogen atoms.
The molecule Carbon Dioxide looks like this
O=C=O
So it has 2 double-bonds in it.
Yes
Yes. H2CO is formaldehyde or methanal. It has two single C-H bonds and a C=O double bond
H2CO; H2CO is polar, whereas CH3CH3 is nonpolar. H2CO has dipole forces in addition to LD forces. CH3CH3 only has LD forces.
