Acid rain is caused due the presence of sulphur dioxide (SO2) and nitrogen dioxide (NO2) Which dissolve in water to form acids like H2SO3 and HNO3.

it's not just cyclohexene, but all alkene molecules that decolourise when react with bromine water. alkenes contain a c=c double bond and thus we call them "unsaturated hydrocarbons". bromine (br2) breaks c=c double bond and attaches itself to the alkene molecule, forming an alkane.
bromine water has a distinctive brown colour.
◦saturated: containing only single carbon-to-carbon bonds.
◦unsaturated: containing at least one double carbon-to-carbon bond.
◦alkenes react spontaneously with bromine water due to their unsaturated nature.
◦the reaction between an alkene and bromine involves the breaking open of the alkene’s double bond and the inclusion of bromine in its structure (an addition reaction).
◦ results in the production of an alkane with two bromine functional groups.
◦therefore, when alkenes come into contact with bromine water, cause it to decolorize.
◦alkanes do not react with spontaneously bromine water due to their saturated nature.
◦bromine is non-polar and therefore dissolves more readily in a non-polar alkane than in polar water.
◦therefore, when alkanes come into contact with bromine water, cause it to decolorize, adopt the colour.
◦if placed in ultraviolet light, a substitution reaction may occur between an alkane and bromine water.
◦ results in the production of hydrogen bromide and an alkane with a single bromine functional group.
◦therefore, when alkanes come into contact with bromine water and are exposed to ultraviolet light, both substances decolorize.
