The compound CH2=CH-CH=CH2 when reacts with HBr gives
1,4 addition product, CH3-CH=CH-CH2Br
ch3-ch2-chcl-chbr-ch3
It is organic as it still only consists of hydrogen and carbon.
Ch3 -ch2 -o-c(o)-ch2-ch2-ch2-ch2-ch2-ch2-ch3
Well, it's organic. Past that it's difficult to say with certainty. It could be a cyclic diether or diol, it could be an ester, it could be an alkene diether or diol ... the molecular formula alone doesn't provide enough information to be sure.
CH2CH2CH2CH2CH2CH2CH2 is an impossible compound formula.CH3CH2CH2CH2CH2CH2CH3 however is called n-heptane (with CH3 at both endings)
Ch3-ch2-ch2-ch2-ch2-ch3
It is organic as it still only consists of hydrogen and carbon.
H2CN2 + heat --> N2 + CH2
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.
The compound Cl-CH2-CH2-CH2-CH=CH-CH2-Br is 1-bromo-6-chloro-2-hexene.
CH2CHOCH3 is methoxyethene.
1. CH2 is the chemical formula of the radical methylene. The structure is H-C-H. 2. The molar mass of CH2 is approx. 14; 168 is an error.
