H2C=C=CH2, 6 sigma and 2 pi bonds.
I assume you mean CH2=C=CH2 or 1,2-propadiene. The molecule has two equally electronegative substituents attached to the central carbon, so no it is not polar. If it was CH2=C=O, then yes it would be polar, because the oxygen atom pulling the electron cloud toward itself, thus making it slightly negative which make he molecule polar.
In a molecule of cumulene, each carbon atom is sp2 hybridized, giving rise to one σ bond between each pair of adjacent carbon atoms. Additionally, there are two π bonds in cumulenes, one above and one below the plane of the molecule due to the consecutive double bonds.
The name of CH2 double bond O is methylene and it is commonly found in aldehydes and ketones, where the carbon is bonded to the oxygen through a double bond.
4-methyl-4-nonene CH3-CH2-CH2-CH(CH3)=CH-CH2-CH2-CH2-CH3 The (CH3) is a methyl group stemming from the CH just before it (#4). - single bond = double bond.
The difference between 2-hexene and 3-hexene lies in the position of the double bond in the hexene molecule. In 2-hexene, the double bond is located on the second carbon atom of the hexane chain, while in 3-hexene, the double bond is located on the third carbon atom of the hexane chain.
4-methyl-4-nonene CH3-CH2-CH2-CH(CH3)=CH-CH2-CH2-CH2-CH3 The (CH3) is a methyl group stemming from the CH just before it (#4). - single bond = double bond.
The molecular shape for CH2=CH2 (ethene) is trigonal planar, with a bond angle of 120 degrees. The carbon atoms are sp2 hybridized, resulting in the planar geometry.

A double bond is a covalent bond where 4 electrons are shared as in H2C=CH2
In a molecule of cumulene, each carbon atom is sp2 hybridized, giving rise to one σ bond between each pair of adjacent carbon atoms. Additionally, there are two π bonds in cumulenes, one above and one below the plane of the molecule due to the consecutive double bonds.
The name of CH2 double bond O is methylene and it is commonly found in aldehydes and ketones, where the carbon is bonded to the oxygen through a double bond.
The structural formula is best displayed as a diagram, similar to H_ ..... _H H_C=C_H or (CH2)(CH2) In C2H4 (ethane, ethene, ethylene) there is a double carbon bond between CH2 structures.
CH3-CH=CH-CH2-CH2-CH2-CH3 if hydrogen of doble bonded carbons are at the same side of plane of double bond then it is cis isomer....
4-methyl-4-nonene CH3-CH2-CH2-CH(CH3)=CH-CH2-CH2-CH2-CH3 The (CH3) is a methyl group stemming from the CH just before it (#4). - single bond = double bond.
The compound CH3CH=CH2 is propene, which is also known as propylene. It is an unsaturated hydrocarbon with a double bond between the second and third carbon atoms in the chain.
3-heptene indicates that the third carbon atom in the seven-carbon chain has a double bond with the fourth carbon atom. H3C-CH2-CH=CH-CH2-CH2-CH3
