Those aren't equal signs, those are double bonds. When there are two double bonds in a compound, it has the suffix: -diene. So, we have 4 carbons, which means it's a but-, and 6 Hydrogens. So the formula is C4H6:
1,3-butadiene
CH2CHOCH3 is methoxyethene.
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
It is 1 fluoropentane.
H2CN2 + heat --> N2 + CH2

CH2CHOCH3 is methoxyethene.
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
1 - bromopropane is the IUPAC name for CH3-CH2-CH2-CH2-Br.
The air distance from ChCh (Christchurch), New Zealand, to Atlanta, Georgia, is 8,370 miles. That equals 13,469 kilometers or 7,273 nautical miles.
It is 1 fluoropentane.
This could be termed as "3-heptene" or "hept-3-ene". Depending on the geometric isomers you could add the prefix cis or trans. If the 2 H atoms are on one side and the hydrocarbon chain on the other side, then it is the cis isomer. If the groups are on either sides , then it is the trans isomer.
H2CN2 + heat --> N2 + CH2
It is organic as it still only consists of hydrogen and carbon.
Cyclopentyl ethyl ester
The compound CH2=CH-CH=CH2 when reacts with HBr gives 1,4 addition product, CH3-CH=CH-CH2Br
H2C=C=CH2, 6 sigma and 2 pi bonds.
