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.
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.
The condensed formula for 2,3,3,4-tetramethylnonane is CH3-CH(CH3)-CH(CH3)-CH2-CH2-CH2-CH2-CH2-CH3.
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.
There 4 isomers : 1) H2C=CHCH2CH3 => but-1-ene 2) CH3CH=CHCH3 => but-2-ene 3) (CH3)2C=CHCH3 => 2- methylpropene 4) CH2-CH2-CH2-CH2 => cyclobutane/cycloalkane. C4h8 has 3 isomers from the same homologous series and one that is not from the same homologous series.
The prefix "hept-" indicates that the molecule contains seven carbon atoms. The number 3 indicates the position of the double bond in the carbon chain. Therefore, "3-heptene" signifies a seven-carbon chain with a double bond at the third carbon.
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....
You think probable to cycloocta-1,5-diene.
ethene: CH2=Ch2 propene: CH2=CH3CH There is nowhere else to place a double bond! (C=C) No number is used in the names ethene and propene because the number would be useless as the double bond is located at carbon "1"
CH3-CH2-CH2-CH=CH2 will be names as 1-pentene or pent-1-ene
CH3CH(Cl)-CH2-CONH2
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 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.
butanal is analdehyde. An oxygen atom is attached to a carbon chain by a double bond and therefre called a carbonyl group. It is found at the end of a carbon atom/chain. CH3-CH2-CH2-CH=O
A double bond is a covalent bond where 4 electrons are shared as in H2C=CH2
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 condensed formula for 2,3,3,4-tetramethylnonane is CH3-CH(CH3)-CH(CH3)-CH2-CH2-CH2-CH2-CH2-CH3.
