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
The IUPAC name for CH2=CH-O-CH3 is ethenyl methoxymethane.
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
The name of the compound CH3CH2CH2CH3 is butane.
Cyclopentyl ethyl ester
It is 1 fluoropentane.

The IUPAC name for CH2=CH-O-CH3 is ethenyl methoxymethane.
1 - bromopropane is the IUPAC name for CH3-CH2-CH2-CH2-Br.
CH2CH2CH2CH2CH2CH2CH2 is an impossible compound formula.CH3CH2CH2CH2CH2CH2CH3 however is called n-heptane (with CH3 at both endings)
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
The name of ch2 gas is methylene.
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.
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.
