H2C=C=CH2, 6 sigma and 2 pi bonds.
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.
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.
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
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
