Chemistry Hydrocarbon

$p_{H_2}=P_T{\chi }_{H_2}$  (P_T = total pressure)

(  ${\chi }_{H_2}$ = mole fraction of H₂)

$p_{O_2}=P_T{\chi }_{O_2}$ ( ${\chi }_{O_2}$  = mole fraction of O₂)

$\frac{p_{H_2}}{p_{O_2}}=\frac{{\chi }_{H_2}}{{\chi }_{O_2}}=\frac{n_{H_2}}{n_{O_2}}$

$n_{H_2}=\frac{1}{2}$  mol

$n_{O_2}=\frac{1}{32}$
$\frac{p_{H_2}}{p_{O_2}}=\frac{1}{2*1}=32$

$\frac{p_{H_2}}{p_{O_2}}=\frac{32}{2}=\frac{16}{1}$

HBr adds to alkene in accordance with Markovnikov's rule.

Delocalisation of  electrons in benzene  leads to saturation

Olefin is a general terms used for unsaturated hydrocarbons such as hydrocarbons which have more than one bond between their carbon atoms. It is derived from the latin word oleum (oil) and facere (make), since these products formed are usually oily in nature.

Also known as arenes, they are a special category of hydrocarbons that have a ring-like structure. These hydrocarbons consist of delocalized pie electrons and are known to be very stable. Benzene is known to be the simplest aromatic hydrocarbon
