Ozone starts its attack at the carbon=carbon double bond(s). This type of bond is ozone's second favorite "meal".
Draw the cyclopentene + H2. Draw the arrow(on top of the arrow type Pd). The result is a cyclopentane (not cyclopentene) For the reaction of Cyclopentene with Br is: Draw the cyclopentene + Br. Draw the arrow; the reaction is 1,2-bromocyclopentane.
Draw the cyclopentene + H2. Draw the arrow(on top of the arrow type Pd). The result is a cyclopentane (not cyclopentene)
Its a cycloalkene
Cyclopentene has a double bond in it. So when it reacts with H20, the double bond will break. In its place, the cyclopentene molecule will gain a OH and an H.

Cyclopentene + bromine => 1,2-dibromocyclopentane
Draw the cyclopentene + H2. Draw the arrow(on top of the arrow type Pd). The result is a cyclopentane (not cyclopentene) For the reaction of Cyclopentene with Br is: Draw the cyclopentene + Br. Draw the arrow; the reaction is 1,2-bromocyclopentane.

Ozone. Normal Oxygen air is O2, and Ozone is O3.
Ultraviolet light constantly renews the ozone layer. As the CFCs are "used up" the ozone should return to its original condition. The Montreal Protocol has limited the addition of fresh ozone depleting substances (ODSs) and this cleanup should occur.
Cyclopentene would be produced from the dehydration of cyclopentanol.
No, burning fossil fuel has little to do with this. The ozone problem was caused by the addition of CFCs (chlorofluorocarbons) to the atmosphere during the 20th century. The Montreal protocol successfully convinced all countries to stop producing CFCs and the ozone layer should have repaired itself by around 2050.
The concentration of ozone in the "ozone layer" varies naturally over some range, based on season and other factors that do not involve the presence of Man. Add in Man's contributing factors, and the concentration of ozone at any point in the "ozone layer" is depressed... allowing more "UV-B" to reach Earth's surface. These factors in the ozone layer can include (in no particular order) reduction in available oxygen, increase in temperature, increase in moisture / humidity, addition of molecules / particulates that will destroy ozone, or molecules / particulates that compete with oxygen molecules for UV more energetic than 215nm .
